RT4803A Overview
Key Specifications
Mount Type: Surface Mount
Pins: 16
Output Type (varies by manufacturer): Adjustable
Length: 1.67 mm
Description
The RT4803A 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. By combining built-in power transistors, synchronous rectification, and low supply current; this IC provides a compact solution for systems using advanced Li-Ion battery chemistries.
Key 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
