Constant frequency peak current mode control step-up converter

Texas Instruments TPS631010 Step-Boost Converter is a constant-frequency peak-current mode controlled step-boost converter in a micro-wafer chip-level package. The step-boost converter has A working output current of 1.5A and an input voltage range of 1.6V to 5.5V. The TPS631010 converter automatically operates in boost, step-down, or 3-cycle step-up-boost mode when the input voltage is roughly equal to the output voltage.

The step-boost converter operates in 8A μ-static current and power saving mode to achieve maximum efficiency under light-load to no-load conditions. The TPS631010 converter is ideal for TWS, system front regulators, load point adjustments, fingerprints, camera sensors, and voltage stabilizers.

Features
