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. The SC630A’s charge pump has three modes of operation: 2x, 1.5x, and 1x modes. The 2x and 1.
