Overview
The S-8338AAHC-P8T1G is a CMOS step-up switching regulator controller from the S-8337/8338 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 1.134 MHz via an external resistor. The device features a maximum duty cycle of 88.5% and includes built-in under-voltage lockout (UVLO) and timer latch short-circuit protection. Packaged in an 8-SON format measuring 2.9 x 2.8 mm, it is designed for portable systems requiring low-voltage operation.
Feature Summary
- Integrates a reference voltage circuit, oscillator, error amplifier, and PWM controller for efficient step-up regulation.
- Includes under-voltage lockout (UVLO) and timer latch short-circuit protection circuits for enhanced system reliability.
- Supports adjustable internal oscillation frequencies up to 1.134 MHz using an external resistor connected to the ROSC pin.
Applications
- Power supply units for LCD displays
- Portable electronic systems operating on low voltages
Procurement Notes
Verify the specific suffix P8T1G against the official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the required switching frequency settings and duty cycle constraints defined in the component documentation before integration into the design.
Selection Notes
Select this component when a low minimum operating voltage of 1.8 V is required for step-up applications. Consider the 8-SON package dimensions and the need for external components to set the oscillation frequency and duty cycle. Verify that the thermal performance meets the requirements for the intended -40°C to 85°C ambient temperature range.
Part Context
This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The series is characterized by its CMOS technology and ability to operate at low input voltages, making it suitable for battery-powered devices. The S-8338 variant specifically offers a maximum duty ratio controllable via an external resistor.
Replacement Considerations
Consult the manufacturer's datasheet for officially confirmed substitute part numbers within the S-8337/8338 family. Verify electrical parameter equivalence and package compatibility before considering any alternative components.
