Voltage Regulators - DC DC Switching Regulators datasheet and documents for MIC4575WU
Voltage Regulators - DC DC Switching Regulators Overview
The MIC4575WU is a BiCMOS step-down (buck) switch-mode voltage regulator manufactured by Microchip Technology. It operates with an input voltage range of 4 V to 24 V and provides a maximum output current of 1 A. The device features a fixed switching frequency of 200 kHz and supports adjustable output voltages. It is housed in a TO-263-5 surface-mount package and functions within a temperature range of -40 °C to +85 °C.
Voltage Regulators - DC DC Switching Regulators Feature Summary
- BiCMOS technology integration for efficient power management
- Fixed 200 kHz switching frequency operation
- Adjustable output voltage capability
Voltage Regulators - DC DC Switching Regulators Applications
- Remote sensing regulators
- General-purpose DC-to-DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the specific suffix 'WU' corresponds to the TO-263-5 surface-mount package configuration. Confirm that the required output voltage aligns with the adjustable variant specifications, as fixed versions exist within the series. Ensure thermal management solutions are adequate for the intended load conditions within the specified operating temperature range.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when a 1 A buck regulator with a 200 kHz frequency is required. It is suitable for applications needing an input voltage up to 24 V. Consider the TO-263-5 package for surface-mount assembly requirements. Verify compatibility with the desired output voltage setting against other MIC4575 variants if fixed outputs are preferred.
Voltage Regulators - DC DC Switching Regulators Part Context
The MIC4575WU belongs to the MIC4575 series of easy-to-use BiCMOS step-down switch-mode voltage regulators. This family includes both fixed and adjustable output options. The WU suffix specifically denotes the surface-mount packaging variant, distinguishing it from through-hole versions like the MIC4575WT.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
MIC4575WT is a through-hole alternative within the same series. LM2575WU offers similar functionality but operates at a different switching frequency of 52 kHz.
