LSP3120 - 3A PWM Buck DC-DC Converter

Download the LSP3120 datasheet PDF. This datasheet also covers the LSP3120_Lite variant, as both devices belong to the same 3a pwm buck dc-dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The LSP3120 series are monolithic IC that design for a step-down DC/DC converter, and own the ability of driving a 3A load without additional transistor component.

Due to reducing the number of external component, the board space can be saved easily.

Key Features

  • Output voltage: 3.3V, 5.0V, 12V, and adjustable output version Adjustable version output voltage range:1.23V to 37V±4% 52KHz±15% fixed switching frequency Voltage mode non-synchronous PWM control Thermal-shutdown and current-limit protection ON/OFF shutdown control input Operating voltage can be up to 40V Output load current: 3A Low power standby mode Built-in switching transistor on chip TO220-5L,TO263-5L packages.
