SC630
Fixed 3.3V High Output Charge Pump Buck/Boost Regulator
POWER MANAGEMENT Features
Description
The SC630 is a high-current voltage regulator using Semtech’s proprietary low-noise charge pump technology. 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 — the head-room needed for voltage regulation. Only two 2.2μF bucket capacitors are required to deliver the full output current. The charge pump provides a low EMI solution compared to inductive buck/boost regulators.
