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 margin up/down controls, pre-bias start-up capability and efficiencies up to 94%. The PTH03050 has an input voltage of 2.95V - 3.65V and offers a wide 0.8V to 2.5V output voltage range with up to 6A output current, which allows for maximum design flexibility and a pathway for future upgrades.

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 0.8V to 2.5V. When the PTH03050 converter leaves the factory the output has been adjusted to the default voltage of 0.8V EFFICIENCY TABLE (IO = 4A) OUTPUT VOLTAGE EFFICIENCY Vo = 1.0V 87% Vo = 1.2V 88% Vo = 1.5V 90% Vo = 1.8V 91% Vo = 2.0V 92% Vo = 2.5V 94% Notes 1 2 3 4 5 6 7 Remote ON/OFF. Active High ON: Pin 3 open; or V > Vin - 0.5V OFF: Pin 3 GND; or V < 0.8V (min - 0.2V). See Figure 1 for safe operating curve. A 100F electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimum of 300mA rms of ripple current. An external output capacitor is not required for basic operation. Adding 100F of distributed capacitance at the load will improve the transient response. 1A/s load step, 50 to 100% Iomax, Cout = 100F. If utilized Vout will track applied voltage by 0.3V (up to Vo set point). The pre-bias start-up feature is not compatible with AutoTrackTM. 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.
