SM8150A 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 life.
