Introduction

AI Translation

The LM46002 SIMPLE SWITCHER regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving load currents up to 2A with an input voltage range of 3.5V to 60V. It delivers excellent efficiency, output accuracy, and dropout voltage in an extremely compact solution size. Peak current mode control is employed for simplified control loop compensation and cycle-by-cycle current limiting. Optional features such as programmable switching frequency, synchronization, power-good flag, precision enable, internal soft-start, adjustable soft-start, and tracking provide flexible and easy-to-use control for a wide range of applications. Discontinuous conduction mode and automatic frequency reduction at light loads improve light-load efficiency. The family requires minimal external components. The device's pinout simplifies and optimizes PCB layout and routing. Protection features include thermal shutdown, VCC UVLO, cycle-by-cycle current limiting, and output short-circuit protection.
