The PM8903A is a high efficiency monolithic step-down switching regulator designed to deliver up to 3 A continuous current. The IC operates from 2.8 V to 6 V input voltage (VIN).
The PM8903A features low-resistance integrated nMOS and proprietary pulse-skipping mode for optimum efficiency over all the loading range.
The voltage mode control loop allows the widest range of output filters. Current sense is internally thermally compensated for optimum precision.
The integrated 0.6 V reference allows the regulation of output voltages with ±1% accuracy over temperature variations. Switching frequency is typically set to 1.1 MHz and can be programmed to 0.8 MHz or 1.0 MHz. Out of phase synchronization allows the reduction of input RMS current.
The PM8903A provides precise dual-threshold overcurrent protection as well as over/undervoltage and overtemperature protection. PGOOD output easily provides real-time information on the output voltage.
The PM8903A is available in VFQFPN16 3 x 3 mm.
