| 3.3 Vin single output DC-DC CONVERTERS * * * * * * * * * * POLA Non-isolated NEW Product 1 6 A output current 3.3 V input voltage Wide-output voltage adjust (0.8 Vdc to 2.5 Vdc) Auto-trackTM sequencing* Pre-bias start-up capability Efficiencies up to 94% Output ON/OFF inhibit Output voltage sense Point-of-Load-Alliance (POLA) compatible Available RoHS compliant PTH03050 The PTH03050 is a next generation series of non-isolated dc-dc converters offering some of the most advanced POL features available in the industry. The primary new feature provides for sequencing between multiple modules, a function, which is becoming a necessity for powering advanced silicon including DSP's, FPGA's and ASIC's requiring controlled power-up and power-down. Other industry leading features include pre-bias start-up capability and efficiencies up to 94%. The PTH03050 has an input voltage of 2.95 Vdc to 3.65 Vdc and offers a wide 0.8 Vdc to 2.5 Vdc output voltage range with up to 6 A output current, which allows for maximum design flexibility and a pathway for future upgrades. All specifications are typical at nominal input, full load at 25 C unless otherwise stated Cin = 100 F, Cout = 0 F OUTPUT SPECIFICATIONS Voltage adjustability Setpoint accuracy Line regulation Load regulation Total regulation Minimum load Ripple and noise 20 MHz bandwidth (See Note 4) 0.8-2.5 Vdc 2.0% Vo 10 mV typ. 12 mV typ. 3.0% Vo 0A 20 mV pk-pk 0.5% Vo GENERAL SPECIFICATIONS Efficiency Insulation voltage Switching frequency Approvals and standards Material flammability Dimensions INPUT SPECIFICATIONS Input voltage range Input current Remote ON/OFF Start-up time Undervoltage lockout Track input voltage Pin 2 (See Note 6, 7) (See Note 3) No load (See Note 1) 2.95-3.65 Vdc 10 mA typ.

It is no longer necessary to purchase a variety of modules in order to cover different output voltages. The output voltage can be trimmed in a range of 0.8 Vdc to 2.5 Vdc. When the PTH03050 converter leaves the factory the output has been adjusted to the default voltage of 0.8 V. Notes Remote ON/OFF. Positive Logic ON: Pin 3 open; or V > Vin - 0.5 V OFF: Pin 3 GND; or V < 0.8 V (min - 0.2 V). 2 See Figure 1 for safe operating curve. 3 A 100 F electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimum of 300 mA rms of ripple current. 4 An external output capacitor is not required for basic operation. Adding 100 F of distributed capacitance at the load will improve the transient response. 5 1 A/s load step, 50 to 100% Iomax, Cout = 100 F. 6 If utilized Vout will track applied voltage by 0.3 V (up to Vo set point). 7 The pre-bias start-up feature is not compatible with Auto-TrackTM. This is because when the module is under Auto-TrackTM control, it is fully active and will sink current if the output voltage is below that of a back-feeding source. Therefore to ensure a pre-bias hold-off, one of the following two techniques must be followed when input power is first applied to the module. The Auto-TrackTM function must either be disabled, or the module's output held off using the Inhibit pin. Refer to Application Note 153 for more details. 8 Tape and reel packaging only available on the surface-mount versions. 9 To order Pb-free (RoHS compatible) surface-mount parts replace the mounting option `S' with `Z', e.g. PTH03050WAZ. To order Pb-free (RoHS compatible) through-hole parts replace the mounting option `H' with `D', e.g. PTH03050WAD. 10 NOTICE: Some models do not support all options.
