Overview
The S-8341C50AFT-T2-U is a CMOS step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 1.8 V to 6 V and provides a fixed output voltage of 5.0 V. The device utilizes Pulse Width Modulation (PWM) control with an internal oscillation frequency of 1.133 MHz. It features a low minimum operating voltage, making it suitable for portable systems. The component is housed in an ultra-small TSSOP-B8 package and includes built-in protection circuits such as under-voltage lockout and timer latch short-circuit protection.
Feature Summary
- Integrates PWM control with a high-frequency internal oscillator for compact design
- Features low minimum operating voltage suitable for single-cell battery applications
- Includes under-voltage lockout and timer latch short-circuit protection circuits
Applications
- Power supply for LCD modules
- Portable electronic devices
- Battery-operated systems
Procurement Notes
Verify the specific suffix 'T2-U' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications and ensure compliance with RoHS directives. Confirm that the fixed 5.0 V output aligns with system requirements before procurement.
Selection Notes
Select this component when a fixed 5.0 V output is required from a single-cell lithium-ion or lithium-polymer battery source. It is appropriate for designs prioritizing small footprint due to the TSSOP-B8 package and requiring basic PWM regulation without external frequency setting.
Part Context
This part belongs to the S-8341 series of step-up switching regulators. It shares architectural similarities with the S-8337/8338 series but offers a fixed output configuration rather than adjustable options. The series targets low-voltage portable applications requiring efficient power conversion.
Replacement Considerations
The S-8337 series may serve as a functional alternative if adjustable output voltage is acceptable. Verify pin compatibility and thermal performance when substituting.
