.Data Sheet.co.kr HT7465 2A Step-Down DC to DC Converter Feature - Input voltage range: 4.75V to 24V - Variable output voltage range: 0.92V to 20V - 2A output current - Efficiency up to 92% - Fixed 380k Hz operating frequency - 20m A shutdown current - Internal power MOSFET switch - Stable operation using low ESR ceramic capacitors - Over temperature protection - Cycle-by-cycle over current protection - Soft-start function - Under voltage lockout protection - 8-pin SOP and 10-pin MSOP package General Description 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 bine to prevent device damage due to overload conditions. In its shutdown mode the regulator draws a mere 20u A of supply current. The device is available in 8-pin SOP and 10-pin MSOP package types and provides a very pact system solution with a minimum of external ponents. Applications - Battery chargers - Distributed power systems - LED power supplies - DSL modems - Linear regulator pre power processing - Set-Top-Boxes, DVD players, LCD displays Application Circuit VIN 4.75~24V 10u F C1 VIN EN SS GND P BS 10n F C2 Efficiency vs Output...
