UNISONIC TECHNOLOGIES CO., LTD UD36061 Preliminary 0.6A, 36V, 2MHZ STEP-DOWN CONVERTER CMOS IC  DESCRIPTION The UTC UD36061 is a high frequency (2MHz) step-down switching regulator with integrated internal high-side high voltage power MOSFET. It regulates input voltages from 3.3V to 36V down to an output voltage as low as 0.8V, and supplies 0.6A highly efficient output with current mode control for fast loop response. In shutdown mode the supply current drops to 3μA, it allows use in battery-powered applications. High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at light load condition to reduce the switching and gate driving losses.
