Overview
SGM2100 Seven-Channel, High Efficiency, DC-DC Power Management Unit GENERAL DESCRIPTION The SGM2100 is a single chip power management unit for a wide range of portable applications.
It incorporates three synchronous switching regulators and four switching regulator controllers in a space saving thin QFN package.
High efficiency, compact size and flexible configuration make SGM2100 the ideal power supply solution for two AA cells or single Li-ion battery powered equipments.
Synchronous switching regulators, SU, SD, & MAIN, provide the core powers for CPU, DSP and I/O.
Switching regulator controllers, AUX1, AUX2, AUX3 and AUX4, coupled with external MOSFETs provide versatile auxiliary powers for image sensor, LCD panel bias, LED backlight, stepping motor, or memory module.
All channels operate at the same programmable constant switching frequency, ranging from 100kHz to 1MHz.
Each channel, with built-in digital soft-start, can be individually selected, and programmed to the desired output voltage with two external resistors.
Power OK, short-circuit flag and thermal protection features provide the system status and extra level of fault protection.
