产品描述
The SGM2101 is a single chip power management unit for a wide range of portable applications. It incorporates three synchronous switching regulators and two switching regulator controllers in a space saving thin QFN package. High efficiency, compact size and flexible configuration make SGM2101 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, AUXA and AUXB, coupled with external MOSFETs provide versatile auxiliary powers for 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.
 
The SGM2101 is available in Green TQFN-7×7-48L package and is rated over the -40°C to +85°C temperature range.
