S-8338ABEC-P8T1G

Overview

The S-8338ABEC-P8T1G is a CMOS step-up switching regulator controller from the ABLIC S-8338 series. It operates within a supply voltage range of 1.8 V to 6 V and supports an internal oscillation frequency up to 1.134 MHz, adjustable via an external resistor. The device utilizes pulse width modulation (PWM) control with a maximum duty cycle of 88.5%. It features built-in under-voltage lockout (UVLO) and timer latch short-circuit protection circuits. The component is housed in an 8-SON package measuring 2.9 x 2.8 mm and is rated for operation between -40°C and 85°C.
