S-8337ACCB-T8T1G

Overview

The S-8337ACCB-T8T1G is a CMOS step-up switching regulator controller from the S-8337 series, manufactured by ABLIC Inc. It operates within a supply voltage range of 1.8 V to 6 V and utilizes pulse width modulation (PWM) control. The internal oscillation frequency is adjustable up to 1.133 MHz via an external resistor connected to the ROSC pin. The maximum duty ratio is configurable through an external resistor on the RDuty pin. Phase compensation and gain are adjusted using components connected to the CC pin. The device is housed in an 8-pin TSSOP package.

Feature Summary

Integrates reference voltage, oscillator, error amplifier, PWM controller, UVLO, and short-circuit protection.
Supports low-voltage operation starting at 1.8 V for portable applications.
Allows external adjustment of oscillation frequency up to 1.133 MHz.
Enables customization of maximum PWM duty ratio via external resistance.

Applications

Power supply for LCD modules
Portable electronic systems operating on low voltage
