SC630A
1MHz Fixed 3.
3V Output Charge Pump
Regulator
POWER MANAGEMENT Features
Description
The SC630A is a high-current voltage
regulator using Semtech’s proprietary low-noise charge pump technology.
The charge pump provides a low EMI solution compared to inductive boost
regulators.
Performance is optimized for use in single Li-Ion battery cell applications.
The
regulator provides the performance of a linear, low drop-out (LDO) voltage
regulator when the battery is greater than 3.
3V.
Unlike an LDO, drop-out is avoided when the battery is less than 3.
3V.
Instead, a charge pump is activated to provide voltage boost and the head-room needed for regulation.
