Overview
The MIC2225-4OYMT is a dual-output voltage regulator featuring a high-efficiency 2MHz PWM synchronous buck converter and a 300mA LDO. It operates from a 2.7V to 5.5V input supply, delivering up to 600mA output current in PWM mode with greater than 95% efficiency. The device includes fully integrated internal power MOSFETs and is available in a 10-pin 2mm x 2mm Thin MLF package. It supports fixed output voltages down to 1V and functions within a junction temperature range of –40°C to +125°C.
Feature Summary
- Integrates a 2MHz synchronous buck regulator and a 300mA LDO for compact dual-rail power solutions
- Provides ultra-low noise performance suitable for sensitive analog and digital loads
- Features thermal shutdown and current limit protection for enhanced system reliability
Applications
- Application processor core and I/O supply rails
- Camera DSP power management
- Multimedia chipset power distribution
Procurement Notes
Verify the specific suffix '4OYMT' against the manufacturer's official datasheet to confirm the fixed output voltage setting and RoHS compliance status. Ensure the ordering code matches the required tape-and-reel packaging quantity. Cross-reference the manufacturer designation, as Micrel products are now distributed under Microchip Technology branding.
Selection Notes
Select this component when space-constrained designs require a combined DC/DC and LDO solution. It is appropriate for applications needing low noise on the LDO rail while maintaining high efficiency on the main buck rail. Verify that the required output voltage corresponds to the fixed option provided by the '4O' suffix variant.
Part Context
This part belongs to the MIC2225 family of ultra-small dual-channel regulators. It is designed to replace discrete power solutions in portable electronics. The device consolidates switching and linear regulation into a single small footprint, reducing board area compared to using separate components.
Replacement Considerations
Compatible alternatives include MIC2225-4MYMT and MIC2225-4SYMT. These variants share the same functional architecture and pinout but may differ in fixed output voltage settings or manufacturing lot specifications.
