RT4803B Product details

Description

The RT4803B allows systems to take advantage of new battery chemistries that can supply significant energy when the battery voltage is lower than the required voltage for system power ICs.

Features

Input Voltage Range: 1.8V to 5V.
Programmable Output Voltage from 2.85V to 4.4V with 50mV/Step.
Default Boost Output Voltage Setting:.
VOUT = 3.4V at VSEL = H.
VOUT = 3.15V at VSEL = L.
Maximum Continuous Load Current: 2A at VIN > 2.65V Boosting VOUT to 3.35V.
Up to 95% Efficiency.
nBYP (L): Forced Bypass Mode.
nBYP (H): Auto Bypass Operation when VIN > Target VOUT.
Internal Synchronous Rectifier.
Overcurrent Protection.
Undervoltage P.
