Microchip Technology, Inc. Integrated Circuits (ICs) - PMIC - Voltage Regulators - DC DC Switching Regulators MIC23603YML-TR

The MIC23603YML-TR is a synchronous buck regulator designed for high efficiency and compact applications. It operates with an input voltage range of 2.7V to 5.5V and can deliver an output current of up to 6A. The device features a switching frequency of 4MHz, which allows for a small footprint and the use of low-profile components, including inductors as small as 0.33¬µH and output capacitors starting at 47¬µF. This regulator achieves peak efficiencies of up to 93% and maintains an efficiency of 81% at a load of 1mA, making it suitable for applications requiring high efficiency at light loads. The quiescent current is low at 24¬µA, and the shutdown current is minimal at 0.01¬µA. The output voltage can be adjusted down to 0.65V, with low output ripple voltage of 5mV in full PWM mode and 14mV in HyperLight Load mode. The MIC23603YML-TR is housed in a compact 20-pin 4mm x 5mm DFN package and is rated for operation over a junction temperature range of -40¬8C to +125¬8C. It includes features such as thermal shutdown, current limit protection, and programmable soft-start, making it a robust choice for various applications including microcontroller power supplies, test and measurement systems, and networking devices.
