1 Introduction
The document describes a non isolated, high power-factor, TRIAC dimmable LED driver designed to drive 36 V at 0.33 A from an input voltage range of 90 VAC to 265 VAC. The LED driver utilizes the LNK405EG device from Power Integrations. The LinkSwitch-PH has been developed to cost effectively design a single-stage power factor corrected LED driver with primary-side constant current control. The LinkSwitch-PH controller was optimized for LED driver applications with minimal external parts count and control of the output current through the LED load without the use of an optocoupler. The LinkSwitch-PH monolithically integrates the 725 V power MOSFET and controller. The controller consists of an oscillator, PWM, 6 V regulator, BYPASS pin programming functions, over-temperature protection, frequency jittering, cycle-by-cycle current limit, leading edge blanking, and charge controller for output CC (constant-current) control. The LinkSwitch-PH also provides a sophisticated range of protection features including auto-restart for control loop open/short faults and output short-circuit conditions. Accurate hysteretic thermal shutdown ensures safe average PCB temperatures under all conditions. The non-isolated power factor corrected buck presented in this report shows how LinkSwitch-PH dramatically simplifies off-line, high-efficiency, power factor corrected LED driver design with very low parts count. This document contains the LED driver specification, schematic, PCB diagram, bill of materials, conducted EMI measurements, thermal measurements, power line transient tests, inductor documentation and typical performance characteristics.

4 Circuit Description
4.1 Non-Dimming, Power Factor Corrected Buck LED Driver The LinkSwitch-PH (U1) is a highly integrated primary side controller intended for use in LED driver applications. The LinkSwitch-PH provides high power factor in a single-stage conversion topology while regulating the output current in a wide range of input and output voltage variations typical in LED driver application environment. All of the control circuitry responsible for these functions plus a high-voltage power MOSFET is incorporated into the device. Capacitor C1, C2, C9, L1, and L2 perform EMI filtering while maintaining high-power factor. This input filter network plus the frequency jittering feature of LinkSwitch-PH easily meets Class B emission limits. Resistor R13 and R12 were used to damp the Q of L1 and L2 for lower EMI. The buck power circuit with floating output connection composed of U1 (power switch + control), D8 (free-wheeling diode), C6 (output capacitor), and L4 (output inductor). Diode D10 was used to prevent negative voltage appearing across drain-source of U1 especially near the zero-crossing of the input voltage. Diode D5 and C3 detect the peak AC line voltage. The voltage across C3 along with R3, R4, and R11 sets input current fed into the V pin. This current is used by U1 to control line undervoltage (UV), overvoltage (OV), and feed-forward current which in conjunction with the FEEDBACK pin current provides constant current to the LED load. The FEEDBACK pin current used by U1 for output voltage feedback is provided by the voltage to current converter network formed by R7-R10, Q2, C5, and D11. Resistor R7 sets the IFB current for a given output voltage. Changes in output voltage are seen by the voltage across R8 which serves as the reference for the current source formed by R7, R8 and Q2. Voltage across R8 was chosen high enough to eliminate or minimize the effect of the temperature and VCE dependence of Q2's VBE voltage. The power Zener VR3 protects the output circuitry during an open load condition. If the load is open for extended period, VR3 will fail short and the unit will enter into auto-restart condition. 4.2 TRIAC Dimmable, Power Factor Corrected Buck LED Driver The board can also be configured for TRIAC dimmable applications. From the original network shown on Figure 3, several circuit blocks need to be added (Figure 4) to enable the power supply to be controlled by a phase-angle controller (TRIAC) and allow the output current, and thus the LED brightness to be controlled. Three networks were added to realize dimming. A damper network formed by R19 and C8 dampens the ringing created by the input capacitance C1-C9 and L1, and L2, every time the TRIAC fires and applies a transient voltage at the input. The network formed by

R14-R17, R25-R26, D6, VR1, VR2, C10 and Q3 provides inrush limiting during TRIAC firing and R25-R26 also helps in damping during the initial stage of the ringing caused by the inrush currents when the TRIAC fires. The third network necessary for dimming applications is the linear regulator formed by R20, R21, R22, R24, R27, Q4, and Q7. This network provides a supply current to the BYPASS pin during periods when the TRIAC is not conducting. 4.3 Minimum Dimming Limitations The minimum dimming angle or TRIAC conduction angle of the driver relies on the TRIAC itself, the BYPASS pin supply current provided by the linear regulator, and the V pin resistor networks which sets UV level of the power supply. Different TRIAC dimmers have different minimum conduction angles and different power ratings which translate to different minimum holding currents. If the TRIAC minimum conduction angle is the limiting factor, the driver will continue to operate at the minimum angle capacity of the TRIAC as long as the UV (line and BYPASS pin) voltage is above their turn-off thresholds. For a dimmer with a small minimum conduction angle, minimum dimming relies on the undervoltage threshold (voltage present at the peak detector) of the design and linear regulator cut-off voltage. For very low TRIAC conduction angles, the peak detector voltage will drop to a low value where the linear regulator configured as a current source may no longer maintain the supply and the unit will shutdown. This shutdown is caused by the BYPASS pin voltage reaching the IC UV threshold. One possible source of power to provide a supply for the BYPASS pin during very low dimming angles is the output itself. As long as the LEDs are conducting a voltage appears across the output and may be used to provide the supply for the BYPASS pin by incorporating a similar network configuration used to feed the FEEDBACK pin. However, these circuit improvements are not covered in this report.
