Overview
The S-8520D29MC-BVOT2G is a CMOS step-down switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 2.5 V to 10 V and delivers a fixed output voltage of 2.9 V. The device utilizes Pulse Width Modulation (PWM) control with a switching frequency of 180 kHz and supports a maximum duty cycle of 100%. Packaged in a compact SOT-23-5 format, it functions across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates PWM control circuitry enabling linear duty ratio variation from 0% to 100% for low ripple and high efficiency.
- Includes built-in error amplifier and soft-start circuit to prevent startup overshoot.
- Supports external Pch power MOS FET or PNP transistor configurations for step-down regulation.
Applications
- Portable electronic devices requiring efficient DC-DC conversion
- Battery-powered systems needing stable regulated voltage
- General-purpose low-voltage power supply circuits
Procurement Notes
Verify the specific suffix BVOT2U against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with required operating temperatures and input voltage ranges before integration. Cross-reference datasheet revision dates to validate current manufacturing status and compliance certifications.
Selection Notes
Select this component when designing non-synchronous buck converters requiring precise PWM control. It is suitable for applications where external power switches are preferred over integrated solutions. Consider the 180 kHz frequency for balancing component size and efficiency requirements.
Part Context
This part belongs to the S-8520 Series, which features CMOS step-down switching regulator controllers. The series is designed to provide high efficiency and excellent transient characteristics through PWM control capabilities, distinguishing it from the S-8521 series which offers PWM/PFM switching modes.
Replacement Considerations
The S-8520E22MC-BJH-T2G is a verified substitute within the same series, offering similar PWM control functionality but with a different fixed output voltage setting.
