Additional Infomation About Product

PM8908 Monolithic buck converter for DDR memory termination Datasheet - production data Applications Memory termination regulator for DDR3, DDR4 and low power DDR3/DDR4 Notebook/desktop/server Low voltage application for 1 V to 3.5 V input QFN20 3.5 x 4.0 mm rails Description Features The PM8908 is a high efficiency monolithic step- down switching regulator designed mainly for the Integrated MOSFETs for high efficiency DDR termination. Current COT architecture The IC operates from 1 V to 3.5 V input voltage 1 V to 3.5 V input voltage (V ) IN (V ). IN 5.0 V supply voltage (V ) CC The device uses a COT control loop that provides Constant frequency mode very good performances in terms of load and line 1% output voltage accuracy transients. The current sense is internally thermally compensated for optimum precision. Two programmable switching frequencies (0.6 MHz or 1 MHz) The output voltage is adjusted from 0.5 V to 2 V with 1% accuracy overtemperature variations. ADJ output voltage from 0.5 V to 2 V Embedded bootstrap diode The PM8908 also provides external tracking support. OV/UV/OC and overtemperature protection The PM8908 provides positive and negative Soft-off with integrated discharge resistor overcurrent protection as well as External tracking over/undervoltage and overtemperature Power Good output protection. PGOOD output easily provides real- time information on the output voltage. QFN20 3.5 x 4.0 mm compact package The PM8908 is available in a QFN20 3.5 x 4.0 mm package. Table 1.
