MIC23031-CYMT-TR

Voltage Regulators - DC DC Switching Regulators Overview

The MIC23031-CYMT-TR is a synchronous buck regulator from Microchip Technology's HyperLight Load series. It operates with an input voltage range of 2.7V to 5.5V and provides a fixed 1V output at up to 400mA. The device utilizes a 4MHz switching frequency and is housed in a compact 6-TMLF (1.6x1.6mm) package. It features high efficiency across the entire load current range, including light-load conditions, and supports operation temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered devices
• Embedded systems requiring efficient power management
• Consumer electronics with space constraints

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific output voltage configuration, as the MIC23031 family includes variants with different fixed outputs (e.g., 1V, 1.5V). Confirm that the 'CYMT' suffix corresponds to the required 1V output version rather than other fixed voltages available in the same package. Ensure compatibility with the target PCB footprint for the 6-TMLF package.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1V output is required within a 2.7V to 5.5V input range. The 4MHz frequency allows for smaller external passive components compared to lower-frequency regulators. Consider the HyperLight Load feature if the application involves significant periods of low current draw to maximize battery life.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MIC23031 family of high-efficiency synchronous buck regulators. The family is characterized by its ability to maintain high efficiency under varying load conditions through proprietary light-load management techniques. The CYMT suffix indicates a specific output voltage variant within the TMLF package lineup.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes may include other MIC23031 variants with different fixed output voltages if the system design allows for adjustment, such as MIC23031-FYMT-TR (1.5V). Verify pinout and thermal characteristics remain identical before substitution.
