MIC45116-1YMP-T1 Microchip

MIC45116 20V/6A DC/DC Power Module Features General Description Up to 6A Output Current The MIC45116 is a synchronous step-down regulator module, featuring a unique adaptive ON-time control >93% Peak Efficiency architecture. The module incorporates a DC/DC Output Voltage of 0.8V to 85% of Input with 1% controller, power MOSFETs, bootstrap diode, bootstrap Accuracy capacitor, and an inductor in a single package Fixed 600 kHz Switching Frequency simplifying the design and layout process for the end Enable Input and Open-Drain Power Good Output user. HyperLight Load (MIC45116-1) Improves Light This highly integrated solution expedites system Load Efficiency design and improves product time-to-market. The Hyper Speed Control (MIC45116-2) Architecture internal MOSFETs and inductor are optimized to Enables Fast Transient Response achieve high efficiency at a low output voltage. The fully Supports Safe Start-Up into Pre-Biased Output optimized design can deliver up to 6A current under a 40C to +125C Junction Temperature Range wide input voltage range of 4.75V to 20V without requiring additional cooling. Thermal Shutdown Protection (HLL) which The MIC45116-1 uses HyperLight Load Short-Circuit Protection with Hiccup Mode maintains high efficiency under light load conditions by Adjustable Current Limit transitioning to variable frequency, discontinuous- Available in 52-Pin 8 mm x 8 mm x 3 mm QFN mode operation. The MIC45116-2 uses Hyper Speed Package Control architecture which enables ultra-fast load transient response, allowing for a reduction of output Applications capacitance. The MIC45116 offers 1% output accuracy High Power Density Point-of-Load Conversion that can be adjusted from 0.8V to 85% of the input Servers, Routers, Networking, and Base Stations (PV ) with two external resistors. Additional features IN FPGAs, DSP, and Low-Voltage ASIC Power include thermal-shutdown protection, adjustable Supplies current limit, and short-circuit protection. The Industrial and Medical Equipment MIC45116 allows for safe start-up into a pre-biased output.
