Introduction

AI Translation

The LM46000 regulator is an easy-to-use synchronous buck DC/DC converter capable of driving load currents up to 500mA with an input voltage range of 3.5V to 60V. The LM46000 delivers excellent efficiency, output accuracy, and dropout voltage in an ultra-compact solution size. The extended family offers 1A and 2A load current options in pin-to-pin compatible packages. Peak current mode control is employed for simplified control loop compensation and cycle-by-cycle current limiting. Optional features include programmable switching frequency, synchronization, power-good flag, precision enable, internal soft-start, adjustable soft-start, and tracking, providing a flexible and easy-to-use platform for a wide range of applications. Discontinuous conduction mode and automatic frequency modulation at light loads improve light-load efficiency. The family requires minimal external components, and the pinout enables simple, optimized PCB layout. Protection features include thermal shutdown, VCC undervoltage lockout, cycle-by-cycle current limiting, and output short-circuit protection. Pin-to-pin compatible with LM46001, LM46002, LM43603, LM43602, LM43601, and LM43600.
