Overview
The S-8520F55MC-BOOT2G is a step-down DC-DC switching controller manufactured by ABLIC Inc. It operates within an input voltage range of 2.5V to 10V and utilizes a fixed 550kHz switching frequency. The device employs pulse-width modulation (PWM) control topology to regulate output voltage. It is housed in a compact SC-74A (SOT-753) package, suitable for surface-mount applications with an operating temperature range of -40°C to 85°C.
Feature Summary
- Fixed-frequency PWM operation for stable regulation
- Integrated enable pin for power management control
- Compact surface-mount packaging for space-constrained designs
Applications
- Portable electronic devices requiring efficient power conversion
- Battery-powered systems utilizing buck topologies
- General-purpose DC-DC step-down regulation circuits
Procurement Notes
Verify the specific suffix BOOT2G against official ABLIC documentation to confirm exact electrical characteristics and availability status. Confirm RoHS compliance and environmental certifications prior to integration. Ensure design compatibility with the specified SC-74A footprint and thermal requirements.
Selection Notes
Select this component when a fixed-frequency synchronous or non-synchronous buck controller is required within a 2.5V to 10V input window. Consider the 550kHz frequency for balancing efficiency and external component size. Verify that the SC-74A package meets the board layout constraints and thermal dissipation needs of the target application.
