Description

The R5313B Series are complete power management system device for cellular phone, especially GSM handset application. The R5313B Series consists of nine voltage regulators, a large current regulator, Li-ion battery charger controller, several protection circuits, and SIM-I/F (can be used as two kinds voltage alternative regulator). The output voltages of all regulators are able to set different output voltage independently by laser trim as well as detector thresholds.

A tiny 48-pin CSP, 0.65mm ball pitch, is available.
