MP9148GJ
DESCRIPTION
The MP9148 is an internally-pensated, 1MHz fixed-frequency, dual PWM, synchronous, step-down regulator. The MP9148 operates from a 2.7V-to-6V input, generates an output voltage as low as 0.608V, and has a 45µA quiescent current that makes it ideal for powering portable equipment that runs on a single cell lithium-ion (Li+) battery.
The MP9148 integrates dual 100mΩ high-side switches and 40mΩ synchronous rectifiers for high efficiency without an external Schottky diode. Peak-current mode control and internal pensation limits the minimum number of readily-available external ponents.
Fault-condition protections include cycle-by-cycle current limiting and thermal shutdown.
The MP9148 is available in an 8-pin TSOT23-8 package.
