S6BP401A
Power Management IC
for Automotive ADAS Platform
Quad Buck 2.1 MHz DC/DC Converter and Dual LDO with Watchdog Timer
S6BP401A is a power management IC, consists of quad buck 2.1 MHz DC/DC converter with built-in switching FETs, dual Low
Drop-out regulator (LDOs) and a digital windowed watchdog timer. Having the switching FETs built-in, S6BP401A realizes high
power conversion efficiency and high switching frequency up to 2.4 MHz. The internal FETs are capable to handle up to 3A load. As
S6BP401A employs the current mode architecture, it has fast load transient response. Built-in output voltage setting resistors and
compensation circuits reduce BOM cost and component area.
