Holtek Semiconductor HT7465
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 current protection and under voltage lockout protection, features which combine to prevent device damage due to overload conditions.| Part No. | HT7465 |
