Overview
The S-8338AABB-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 device features an internal oscillator with a frequency settable up to 1.133 MHz via an external resistor on the ROSC pin. Packaged in an 8-pin TSSOP format, it integrates reference voltage circuits, error amplifiers, under-voltage lockout (UVLO), and timer latch short-circuit protection.
Feature Summary
- Integrates UVLO and timer latch short-circuit protection for enhanced system reliability
- Supports high-frequency operation with PWM control adjustable up to 1.133 MHz
- Enables low-voltage operation starting at 1.8 V for portable applications
Applications
- Power supply units for LCD displays
- Portable electronic systems requiring low voltage operation
- Step-up DC-DC converter designs
Procurement Notes
Verify the specific output voltage setting associated with the AABB suffix against the official datasheet before procurement. Confirm package integrity and RoHS compliance status through manufacturer documentation. Ensure ordering quantities align with standard reel packaging requirements specified by ABLIC Inc.
Selection Notes
Select this component when designing boost converters requiring a wide input voltage range down to 1.8 V. The adjustable oscillation frequency allows optimization for external component size versus efficiency trade-offs. Verify that the required output voltage matches the fixed setting defined by the part suffix.
Part Context
This controller belongs to the S-8337/8338 series of high-frequency step-up switching regulators. The series is designed for portable equipment, offering a compact solution with integrated protection circuits. The T8T1G suffix indicates the specific TSSOP-8 package configuration and tape-and-reel shipping method.
Replacement Considerations
S-8338ABEB-T8T1G: Different fixed output voltage setting. S-8338ACGA-T8T1G: Different fixed output voltage setting. S-8338ABEC-T8T1G: Different fixed output voltage setting.
