PG-DSO-8
Description The TLE8366 is a PWM step-down DC/DC converter with an integrated 1.8 A power switch, packaged in a small PG-DSO-8 with exposed pad. There are three versions available, two fixed voltage with 5.0 V (TLE8366EV50) or 3.3 V (TLE8366EV33) and a variable voltage variant named TLE8366EV with a reference feedback voltage of only 600 mV. The wide input voltage range from 4.75 to 45 V makes the TLE8366 suitable for a wide variety of applications. The device is designed to be used under harsh automotive environment. The switching frequency of nominal 370 kHz allows the use of small and cost-effective inductors and capacitors, resulting in a low, predictable output ripple and in minimized consumption of board space. (If desired the device could be synchronized to an external frequency source between 200 and 530 kHz.) The TLE8366 includes safety features such as a cycle-by-cycle current limitation, over-temperature shutdown and input under voltage lockout. The enable function, in shutdown mode with less than 2 A current consumption, enables easy power management in battery-powered systems. The voltage regulation loop provides an excellent line and load regulation. The stability of the loop could be adjusted by using an external compensation network. This compensation network combined with voltage mode regulation and a feed-forward control path guarantees a highly effective line transient rejection. During start-up the integrated soft-start limits the inrush current peak and prevents from a voltage overshoot.

Buck Regulator
Description
5.1.1
Arrangement
The step-down (or buck) regulator consists of several functional blocks, which shall be explained in the following: The oscillator, the regulator, the safety functions, the gate driver and the internal MOSFET.
5.1.1.1
Regulator Block
The oscillator creates a saw-tooth signal, which is supplied to the PWM comparator and the Schmitt-Trigger 1. The frequency of the oscillator might be synchronized to an external frequency connected to pin sync. The Error Amplifier compares the feedback signal to the reference voltage. At the variable voltage version the feedback pin shall be connected to an external resistor divider, the fixed voltage versions contain an internal resistor divider. The soft start function is included by the ramp generator between the reference voltage source and the error amplifier. It generates a defined ramp after the initialization of the device. (The device is initialized after signal EN turns to high (with supply voltage at VS present) or with rising Supply voltage (with EN = H connected to VS) or at restarting after a thermal shutdown. The ramp starts, if the Buck Driver Supply (BDS) external capacitor is charged. Only for the variable voltage version: If the feedback signal at pin FB gets lost, an internal pull-up current source will pull the pin too high thus preventing the output voltage from overshooting. A compensation network needs to be connected to the output of the error amplifier using pin COMP. The PWM comparator creates the Pulse-Width Modulated (PWM) signal by comparing the error amplifier output with the saw-tooth signal from the oscillator.
5.1.1.2
Safety Functions Block
The safety functions block consists of the Error-Flip Flop, the Nor1 Gate and the PWM-Flip-Flop. The Error Flip-Flop collects the failure events such as the over-current shutdown of the internal MOSFET, the output overvoltage shutdown and the temperature shutdown. The over-current shutdown signal is created by the OC comparator. It detects the voltage across an internal shunt resistor. If the current exceeds the reference level, the pulse is shut down and the MOSFET switched off. The bootstrap under-voltage shutdown is created by the BDS UV comparator, which compares the bootstrap capacitor voltage to a reference level. If the bootstrap capacitor voltage is too low, the pulse will be shut down and the MOSFET switched off. If the output voltage exceeds a reference value, the pulse will also be shut down and the MOSFET switched off.
Data sheet

Rev. 1.0, 2009-05-18
TLE8366
Buck Regulator An internal temperature sensor detects the temperature of the device, it will be switched off if the junction temperature exceeds 175 C. The error Flip flop is set by the Schmitt Trigger 1 and will be reset by one of these signals. This will close the NOR1 gate and shutdown the pulse. The bootstrap capacitor monitoring is connected directly to the NOR1 gate. The bootstrap under-voltage shutdown is created by the BDS UV comparator, which compares the bootstrap capacitor voltage to a reference level. If the bootstrap capacitor voltage is too low, the pulse will be shut down. PWM pulses are passing through the NOR 1 gate. In case if one of the mentioned failures will occur this gate will be closed and the pulse switched immediately off. The PWM Flip-Flop is set by NAND2, which combines the clock from the Schmitt Trigger 1 with the output from NOR1. The PWM Flip-Flop is reset by the output of the NOR1.
5.1.1.3
Internal Power Stage
The gate driver consists of the Gate driver itself, an inverter for the PWM signal and the gate driver supply. The gate Driver Supply is connected over pin BDS to the BDS capacitor. A charge pump is integrated to support the gate drive in cases of low input voltage, small differential voltage between input supply and output voltage and during start up. To minimize emissions the charge pump is switched off if the input voltage is high enough to charge the bootstrap capacitor.
5.1.2
Operation Mode
The PWM pulses are voltage controlled. The error amplifier and the PWM comparator are creating the PWM pulses using the oscillator saw-tooth signal and the feedback voltage. The pulse-width modulation is done so that the feedback voltage (at pin FB for the adjustable version) is similar to the reference voltage (0.6 V). Between input voltages from 8.0 to 36 V the integrated feed forward path provides a fast line transient rejection. (feed-forward means sensing the input voltage and react on fluctuations before they influence the output) To achieve a stable output voltage even under low duty cycle conditions (light load down to zero output load and/or high input voltage) a pulse skipping mode is implemented. Pulse skipping is also used for operation with low supply voltages leading to duty cycles > 92%.

Module Enable and Thermal Shutdown
Description
With the enable pin the device can be set in off-state reducing the current consumption to less than 2A. The enable function features an integrated pull down resistor which ensures that the IC is shut down and the power switch is off in case the pin EN is left open. The integrated thermal shutdown function turns the power switch off in case of overtemperature. The typ. junction shutdown temperature is 175C, with a min. of 160C. After cooling down the IC will automatically restart operation. The thermal shutdown is an integrated protection function designed to prevent IC destruction when operating under fault conditions. It should not be used for normal operation.

7.1
Module Oscillator
Description
The oscillator supplies the device with a constant frequency. The power switch will be switched on and off with a constant frequency. The duty-cycle is derived from this frequency and some safety functions are synchronized to this frequency. The internal sawtooth signal used for the PWM generation has an amplitude proportional to the input supply voltage (feedforward). The turn-on frequency can optionally be set externally via the 'SYNC' pin. In this case the synchronization of the PWM-on signal refers to the falling edge of the 'SYNC'-pin input signal. In case the synchronization to an external clock signal is not needed the 'SYNC' pin should be connected to GND. Leaving pin SYNC open or short-circuiting it to GND leads to normal operation with the internal switching frequency.

Application Information
Note: The following information is given as a hint for the implementation of the device only and shall not be regarded as a description or warranty of a certain functionality, condition or quality of the device.
8.1
Frequency Compensation
The stability of the output voltage can be achieved with a simple RC connected between pin COMP and GND. The standard configuration using the swiching frequency of the internal oscillator is a ceramic capacitor CCOMP = 22nF and RCOMP = 22k. By slight modifications to the compensation network the stability can be optimized for different application needs, such as varying switching frequency (using the sychronizing function), different types of buck capacitor (ceramic or tantalum) etc. The compensation network is essential for control loop stability. Leaving pin COMP open might lead to instable operation.
8.2
Compensating a tantalum buck capacitor CBU1
The control loop is optimized for use of ceramic buck capacitors CBU. In order to maintain stability also for tantalum capacitors with ESR up to 300m, an additional compensation capacitance CCOMP2 at pin COMP to GND is required. It's value calculates:
CCOMP2 = CBU * ESR(CBU) / RCOMP ,
whereas CCOMP2 needs to stay below 5nF.
