MIC45208-1/-2  
26V, 10A DC-to-DC Power Module  
Features  
General Description  
• No Compensation Required  
• Up to 10A Output Current  
• >93% Peak Efficiency  
• Output Voltage: 0.8V to 0.85*VIN with  
±1% Accuracy  
• Adjustable Switching Frequency from 200 kHz to  
600 kHz  
• Enable Input and Open-Drain Power Good (PG)  
Output  
• Hyper Speed Control® (MIC45208-2) Architecture  
enables Fast Transient Response  
• HyperLight Load® (MIC45208-1) improves Light  
Load Efficiency  
The MIC45208-1/-2 is a synchronous, step-down regula-  
tor module, featuring a unique adaptive ON-time control  
architecture. The module incorporates a DC-to-DC  
controller, power MOSFETs, bootstrap diode, bootstrap  
capacitor and an inductor in a single package, simplifying  
the design and layout process for the end user.  
This highly integrated solution expedites system  
design and improves product time-to-market. The  
internal MOSFETs and inductor are optimized to  
achieve high efficiency at a low-output voltage. The  
fully optimized design can deliver up to 10A current  
under a wide input voltage range of 4.5V to 26V,  
without requiring additional cooling.  
• Supports Safe Start-up into Pre-Biased Output  
• –40 C to +125°C Junction Temperature Range  
• Thermal Shutdown Protection  
• Short-Circuit Protection with Hiccup mode  
• Adjustable Current Limit  
The MIC45208-1 uses the HyperLight Load (HLL) while  
the MIC45208-2 uses Hyper Speed Control (HSC) archi-  
tecture, which enables ultra-fast load transient  
response, allowing for a reduction of output capacitance.  
The MIC45208 offers 1% output accuracy that can be  
adjusted from 0.8V to 0.85*VIN with two external  
resistors. Additional features include thermal shutdown  
protection, input undervoltage lockout, adjustable  
current limit and short-circuit protection. The MIC45208  
allows for safe start-up into a pre-biased output.  
• Available in 52-Pin 10 mm x 10 mm x 4 mm QFN  
Package  
Applications  
• High-Power Density Point-of-Load (POL)  
Conversion  
Data sheet and other support documentation can be  
found on the Microchip web site at: www.microchip.com.  
• Servers, Routers, Networking and Base Stations  
• FPGAs, DSP and Low-Voltage ASIC Power Supplies
