Overview
The S-8338AAGA-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 on the ROSC pin. The maximum duty ratio is fixed at 88%. The device includes an under-voltage lockout circuit and timer latch short-circuit protection. It is housed in an 8-pin TSSOP package.
Feature Summary
- Integrates reference voltage, oscillator, error amplifier, and PWM controller for efficient power management.
- Features low minimum operating voltage suitable for portable systems and LCD power supplies.
- Includes built-in under-voltage lockout and timer latch short-circuit protection circuits.
Applications
- Power supply for liquid crystal displays
- Portable electronic systems requiring low voltage operation
Procurement Notes
Verify the specific suffix 'AAGA' against official ABLIC documentation to confirm exact electrical characteristics and availability status. Confirm RoHS compliance details as specified in the latest datasheet revision. Ensure the ordering part number matches the required package type and factory pack quantity before finalizing procurement orders.
Selection Notes
Select this component when a fixed maximum duty ratio is acceptable for the boost converter design. The S-8338 series differs from the S-8337 series by having a fixed duty ratio rather than an externally adjustable one. Consider the adjustable frequency capability via the ROSC pin for optimizing external component size and efficiency requirements.
Part Context
This part belongs to the S-8337/8338 Series of high-frequency PWM control switching regulator controllers. These devices are designed as CMOS step-up regulators ideal for applications requiring low input voltages. The series provides essential protection features and stable operation through adjustable phase compensation components connected to the CC pin.
Replacement Considerations
The S-8337 series serves as a functional alternative if external adjustment of the maximum duty ratio is required instead of the fixed ratio found in the S-8338 series. Verify pin compatibility and electrical specifications before substituting with other models in the ABLIC portfolio.
