Microchip Technology, Inc. DC DC Switching Controllers MIC24420YML-TR

The MIC24420YML-TR is a synchronous PWM dual output step-down converter designed for high efficiency in low duty-cycle applications. It features internal 2.5A high-side switches and an integrated low-side gate driver, allowing for synchronous operation with external N-channel MOSFETs. The device operates with an input voltage range of 4.5V to 15V and supports adjustable output voltages down to 0.7V. The switching frequency is set at 1MHz, which is beneficial for applications requiring fast response times. This regulator offers a 2% output voltage tolerance across a temperature range of -40¬8C to +125¬8C, ensuring reliable performance in various environments. It includes features such as programmable maximum current limit, power good output for voltage sequencing, and ramp control for soft-start capabilities. The MIC24420YML-TR is housed in a compact 24-pin 4mm x 4mm MLF package, making it suitable for space-constrained designs. Typical applications include multi-output power supplies, DSP, FPGA, CPU, and ASIC power supplies, as well as telecom and networking equipment.
