PM8903TR : The PM8903 is a high efficiency monolithic stepdown 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 PM8903 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 filter. 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.

PM8908 : The PM8908 is a high efficiency monolithic stepdown switching regulator designed mainly for the DDR termination. The IC operates from 1 V to 3.5 V input voltage (VIN). The device uses a COT control loop that provides very good performances in terms of load and line transients. The current sense is internally thermally compensated for optimum precision. The output voltage is adjusted from 0.5 V to 2 V with ± 1% accuracy overtemperature variations. The PM8908 also provides external tracking support. The PM8908 provides positive and negative overcurrent protection as well as over/undervoltage and overtemperature protection. PGOOD output easily provides realtime information on the output voltage.
