MSAP3032KTR-G1

The MSAP3032KTR-G1 is a boost converter designed to drive series-connected white LEDs powered by a single-cell Li-ion battery, supporting up to 7 LEDs. The device employs a current-mode, fixed-frequency architecture that regulates LED current via an external current-sense resistor. Its feedback voltage as low as 200mV helps reduce power dissipation and improve efficiency. The device integrates undervoltage lockout, current limiting, and thermal overload protection to prevent damage during output overload conditions. The optimized operating frequency accommodates compact LC filters and low operating current while maintaining high efficiency. An internal soft-start function reduces inrush current. The compact package offers an optimal solution for PCB space savings and reduced total BOM cost.
