PMIC with White LED Driver
1. OVERVIEW
The SM8150A is a charge pump type white LED driver, with 2-system programmable LDOs (Low Dropout
Regulator), and step-down DC/DC converter power management IC. The white LED driver provides constant-
current drive for 1 to 6 backlight white LED connected in parallel and 1 torch/strobe white LED. The charge
pump automatically selects between
×1 mode, ×1.5 boost mode, and ×2 boost mode in response to battery volt-
age, LED drive current, and VFLED (LED forward bias voltage drop) conditions in order to extend battery
drive life. The SM8150A operating mode settings are accessed using an I2C*1 interface, allowing LED drive
current, LDO voltage, output ON/OFF, and other settings to be controlled from a microcontroller.
