Overview
The S-8338ACDC-P8T1G is a CMOS step-up switching regulator controller from ABLIC Inc., designed for portable systems and LCD power supplies. It operates within a supply voltage range of 1.8V to 6V and supports an adjustable internal oscillation frequency between 257.4kHz and 1.134MHz. The device features a maximum duty ratio of 88.5% and includes control characteristics such as current limiting, enable functionality, and frequency control. It is housed in an 8-SON(A) package measuring 2.9x2.8mm and functions with positive output configuration.
Feature Summary
- Integrates under voltage lockout circuit (UVLO) and timer latch short-circuit protection circuit
- Supports external frequency setting via resistor connected to ROSC pin
- Includes error amplifier and PWM controller for stable regulation
Applications
- Power supply for LCD modules
- Portable electronic systems operating on low voltage
- Step-up DC-DC converter designs
Procurement Notes
Verify the specific suffix P8T1G corresponds to the 8-SON(A) package variant when sourcing. Confirm RoHS compliance status against the latest manufacturer documentation. Check component availability status as some listings indicate it may not be recommended for new designs due to potential minimum order quantity restrictions or lifecycle changes.
Selection Notes
Select this component for applications requiring a compact boost controller with low minimum operating voltage. Ensure the external oscillator resistor allows the switching frequency to fall within the specified 257.4kHz to 1.134MHz range. Verify that the required duty cycle does not exceed the 88.5% maximum limit for the intended input-output voltage differential.
Part Context
This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The S-8338 variant specifically provides a maximum duty ratio of 88.5%, distinguishing it from the S-8337 series which typically offers up to 89%. Both series share similar internal architectures including reference voltage circuits and UVLO.
Replacement Considerations
S-8338ACCC-T8T1G: Alternative version in TSSOP-8 package. S-8338ABEA-P8T1G: Alternative version in 8-SON(A) package. S-8338AADB-P8T1G: Alternative version in 8-SON(A) package.
