Overview
The S-8338AAHA-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series, manufactured by ABLIC Inc. It operates with an input voltage range of 1.8 V to 6 V and supports a maximum switching frequency of 1.134 MHz. The device features a fixed maximum duty ratio of 88.5% and utilizes pulse width modulation (PWM) control. It is housed in an 8-SON package measuring 2.9x2.8 mm and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates UVLO and timer latch short-circuit protection circuits for enhanced system reliability.
- Allows external adjustment of oscillation frequency via the ROSC pin up to 1.134 MHz.
- Supports phase compensation and gain value tuning through external RC components connected to the CC pin.
Applications
- Power supply systems for LCD displays
- Portable electronic devices requiring low-voltage operation
- Step-up DC-DC converter designs
Procurement Notes
Verify the specific suffix P8T1G against official datasheets to confirm the exact package variant and reel configuration. Ensure compatibility with the required operating temperature range and input voltage specifications before integration into final designs.
Selection Notes
Select this component when a fixed duty cycle of 88.5% is acceptable for the boost topology. Consider the S-8337 series if adjustable maximum duty ratios are required for different output voltage configurations or load conditions.
Part Context
This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The series is designed for applications needing efficient power conversion at frequencies up to 1.2 MHz while maintaining a low minimum operating voltage.
