HT7465中文资料2A Step-Down DC to DC Converter数据手册Holtek规格书

描述 Description

The HT7465 is a 2A high efficiency step-down DC-DC 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 current protection and under voltage lockout protection, 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 package types and provides a very compact system solution with a minimum of external components.
