S-8520F55MC-BOOT2U

Overview

The S-8520F55MC-BOOT2U is a CMOS step-down switching regulator controller from the S-8520 series, manufactured by ABLIC. It operates with a fixed PWM control mode and supports an input voltage range of 2.5 V to 16 V. The device provides a fixed output voltage of 5.5 V and functions at a switching frequency of 300 kHz. It features a low quiescent current of 100 uA and is rated for operation within a temperature range of -40 C to +85 C. The component is housed in an SOT-23 package.

Feature Summary

Fixed pulse-width modulation (PWM) control architecture
Integrated reference voltage source and oscillation circuit
Low quiescent current consumption for efficiency

Applications

Battery-powered portable devices
General-purpose DC-DC conversion systems
Embedded power management circuits

Procurement Notes

Verify the exact suffix BOOT2U against official ABLIC documentation to confirm pinout and electrical specifications. Ensure compatibility with external MOSFETs and passive components based on the 300 kHz switching frequency. Confirm RoHS compliance status through the manufacturer's datasheet before integration into production designs.

Selection Notes

Select this controller when a fixed 5.5 V output is required from a 2.5 V to 16 V input source. It is suitable for applications prioritizing simplicity over adjustable regulation due to its fixed output design. Consider the S-8521 series if programmable PWM/PFM switching modes are needed instead of fixed PWM operation.

Part Context

This component belongs to the S-8520/8521 series of CMOS step-down switching regulator controllers. The S-8520 series specifically utilizes fixed PWM control, distinguishing it from the S-8521 series which offers switchable PWM/PFM modes. Both series share similar internal architectures including error amplifiers and reference sources.
