S-8337ABCA-P8T1G

Overview

The S-8337ABCA-P8T1G is a CMOS step-up switching regulator controller from the S-8337 series, manufactured by ABLIC Inc. It operates within an input voltage range of 1.8 V to 6 V and supports a maximum oscillation frequency of 1.133 MHz via an external resistor on the ROSC pin. The device utilizes pulse width modulation (PWM) control with a maximum duty ratio adjustable through an external resistor connected to the RDuty pin. Phase compensation and gain are configurable using external components on the CC pin. It is housed in an 8-SON package.

Feature Summary

• Integrates reference voltage circuit, oscillator, error amplifier, PWM controller, UVLO, and short-circuit protection.
• Allows flexible configuration of internal oscillation frequency up to 1.133 MHz via external resistor.
• Enables adjustment of maximum PWM duty ratio through external resistor connection.

Applications

• Power supply for LCD displays
• Portable systems operating on low voltage
