S-8338AACA-P8T1G

Overview

The S-8338AACA-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series, manufactured by ABLIC Inc. It operates within an input voltage range of 1.8 V to 6 V and utilizes pulse width modulation (PWM) control. The device supports an internal oscillation frequency adjustable up to 1.133 MHz via an external resistor connected to the ROSC pin. It features a timer latch short-circuit protection circuit and under-voltage lockout (UVLO). The component is housed in an 8-SON package with dimensions of 2.9 mm x 2.8 mm.

Feature Summary

• Integrates a reference voltage circuit, oscillator, error amplifier, and PWM controller for efficient power management.
• Includes a timer latch short-circuit protection circuit to enhance system reliability during fault conditions.
• Supports low-voltage operation starting at 1.8 V, suitable for portable systems.

Applications

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

Procurement Notes
