S-8338ABFC-P8T1G

Overview

The S-8338ABFC-P8T1G is a CMOS step-up switching regulator controller from the ABLIC S-8338 series. It operates with a minimum input voltage of 1.8 V and supports an internal oscillation frequency adjustable up to 1.134 MHz via an external resistor on the ROSC pin. The device utilizes pulse width modulation (PWM) control with a maximum duty ratio of 88.5%. It features built-in under-voltage lockout, timer latch short-circuit protection, and current limit functions. Packaged in an 8-SON format, it is designed for low-voltage portable applications.
