HT7465 - Holtek Semiconductor

HT7465 2A Step-Down DC to DC Converter

The HT7465 is a 2A high efficiency step-down DCDC converter which includes a fully integrated MOS power transistor. The device uses a current-mode control operating methodology and can operate over a wide input voltage range of 4.75V to 24V for which it can provide a stable adjustable output voltage. The device includes over temperature protection, over curr.

Features

which combine to prevent device damage due to overload conditions. In its shutdown mode the regulator draws a mere 20uA of supply current. The device is available in 8-pin SOP and 10-pin MSOP package types and provides a very compact system solution with a minimum of external components. Applications
