Microchip Technology, Inc. PMIC - PMIC - Voltage Regulators - DCDC Switching Controllers - MIC2169YMM-TR MIC2169YMM-TR

The MIC2169YMM-TR is a high-efficiency synchronous buck control IC designed for DC/DC conversion applications. It operates with an input voltage range of 3V to 14.5V and can regulate output voltages down to 0.8V. The device features a 500kHz PWM operation and achieves efficiencies exceeding 95% across a wide load range, thanks to its adaptive all N-Channel MOSFET drive scheme. This IC eliminates the need for an external current-sense resistor by sensing current across the high-side MOSFET, which also helps maintain current limit accuracy. It includes built-in in-rush current limiting and digital soft-start functionality, contributing to reduced component count and overall cost. The MIC2169YMM-TR is housed in a compact 10-pin MSOP package and operates within a junction temperature range of -40¬8C to +125¬8C. Typical applications include point-of-load DC/DC conversion for devices such as graphic cards, set-top boxes, and telecom power supplies. The product also features overvoltage protection and hiccup mode short-circuit protection, enhancing its reliability in various applications.
