Unisonic Technologies UD36061
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. The converter uses internal N-Channel MOSFET switches to step-down the input voltage to the regulated output voltage.| Part No. | UD36061 |

DESCRIPTION
The UTC 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. Since the high side MOSFET requires a gate voltage greater than the input voltage, a boost capacitor connected between SW and BST is needed to drive the high side gate. The boost capacitor is charged from the internal 5V rail when SW is low. Frequency fold-back helps prevent inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation.●
