Overview
The S-8338AAIA-T8T1G 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 internal oscillation frequency is adjustable up to 1.133 MHz via an external resistor connected to the ROSC pin. This specific variant features a fixed maximum duty ratio of 88%. It is housed in an 8-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates under-voltage lockout and timer latch short-circuit protection circuits for enhanced system reliability.
- Allows phase compensation and gain adjustment through external resistors and capacitors connected to the CC pin.
- Supports low-voltage operation starting at 1.8 V, suitable for portable systems.
Applications
- Power supply for LCD modules
- Portable electronic devices requiring low voltage operation
Procurement Notes
Verify the complete part number including suffixes such as T8T1G against official ABLIC documentation to ensure correct packaging and specifications. Confirm RoHS compliance status and check for any Product Change Notifications (PCN) regarding material or manufacturing process updates before finalizing procurement orders.
Selection Notes
Select this component when a fixed maximum duty ratio of 88% is required for boost converter designs. Choose the TSSOP-8 package if board space allows for larger footprints compared to SON options. Ensure the application requires PWM control rather than frequency modulation variants found in other series members.
Part Context
This device belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. While the S-8337 series allows variable maximum duty ratios via external resistors, the S-8338 series fixes this parameter internally. The AAIA suffix indicates specific factory settings within the broader S-8338 product family.
Replacement Considerations
S-8338ABEC-T8T1G shares the same TSSOP-8 package and core functionality but may differ in specific factory-set parameters or revision levels. Verify electrical characteristics and pin compatibility with the official datasheet before substitution.
