Evaluation Board for MIC28510 5V 75V/4A Hyper Speed Control™ DC/DC Regulator

The Micrel MIC28510 is an adjustable frequency, synchronous buck regulator featuring unique adaptive on–time control architecture.

Hyper Speed Control™ architecture enables 
High delta V operation (Vin = 75V and Vout = 0.8V) 
Small output capacitance 
4.5V to 75V voltage input 
4A output current capability, up to 95% efficiency 
Output voltage set at 5V
≤1% feedback accuracy 
Any Capacitor™ stable 
Zero-ESR to high-ESR output capacitors 
100kHz to 500kHz switching frequency 
Internal compensation 
Foldback current-limit and “hiccup” mode short-circuit protection 
Thermal shutdown 
Supports safe startup into a pre–biased load
