Overview
LV2862 SNVSA49B – JANUARY 2015 – REVISED JUNE 2023 LV2862 60-V, 600-mA, High-Efficiency, Wide Input Voltage Range Buck Converter 1 Features • Input range from 4 V to 60 V with 65-V transients • 770-kHz (X version) or 2.
1-MHz (Y version) switching frequency • Ultra-high efficiency for light load with Eco-mode • Low dropout operation • Output current up to 600 mA • High-voltage precision enable input • Overcurrent protection • Overtemperature protection • Internal compensation • Internal soft start • Small overall solution size (SOT-6L package) 2 Applications • Grid infrastructure • Appliances • Motor drive • General purpose wide VIN power supplies 3 Description The LV2862 is a PWM DC/DC buck (step-down) regulator.
With a wide input range from 4 V to 60 V, the device is designed for a wide range of applications, from industrial to automotive, for power VIN Up to 60 V Cin VIN SHDN GND LV2862 CB Cboot L1 SW D1 R1 FB Cout R2 Simplified Schematic conditioning from unregulated source.
An ultra-low 1-µA shutdown current can further prolong battery life.
Operating frequency is fixed at 770 kHz (X version) and 2.
1 MHz (Y version), allowing the use of small external components while still being able to have low output ripple voltage.
Soft start and compensation circuits are implemented internally, which allows the device to be used with minimized external components.
The LV2862 is optimized for up to 600-mA load currents.
The device has a 0.
765-V nominal feedback voltage.
The device has built-in protection features such as pulse-by-pulse current limit, thermal sensing, and shutdown due to excessive power dissipation.
The LV2862 is available in a low profile SOT-6L package.
