Description and Introduction
InputV: 0.3-20V; 50mA; high efficiency synchronous step-down switching regulator. For notebook and palmtop computers, portable instrumnets, battery operated digital devices The ADP1148AN-3.3 is a step-down DC-DC switching regulator manufactured by Analog Devices (AD). It is designed to provide a fixed 3.3V output from an input voltage range of 4.5V to 30V. The device can deliver up to 5A of output current and operates at a switching frequency of 200 kHz. It features a synchronous rectification architecture, which improves efficiency and reduces the need for external components. The ADP1148AN-3.3 includes overcurrent protection, thermal shutdown, and undervoltage lockout to ensure reliable operation. It is available in an 8-lead PDIP (Plastic Dual In-line Package) and is suitable for a variety of applications, including distributed power systems, portable instruments, and telecommunications equipment.

Description and Introduction
InputV: 0.3-20V; 50mA; high efficiency synchronous step-down switching regulator. For notebook and palmtop computers, portable instrumnets, battery operated digital devices The ADP1148AN-3.3 is a synchronous step-down DC-to-DC converter manufactured by Analog Devices Inc. (ADI). It is designed to provide a fixed output voltage of 3.3V. The device operates over an input voltage range of 5.5V to 30V and can deliver output currents up to 5A. It features a high switching frequency of up to 200 kHz, which allows for the use of smaller external components. The ADP1148AN-3.3 includes built-in protection features such as overcurrent protection, thermal shutdown, and undervoltage lockout. It is available in an 8-pin PDIP (Plastic Dual In-line Package) and is suitable for a variety of applications, including distributed power systems, industrial equipment, and telecommunications.
