LA8040 - 5V 2A Synchronous Step-Down Converter

Download the LA8040 datasheet PDF. This datasheet also covers the LA8040-INNO variant, as both devices belong to the same 5v 2a synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The LA8040 is a current mode, synchronous step-down DC-DC converter that is designed to meet 2A output current, and utilizes PWM control scheme that switches with 1MHz fixed frequency.

The input voltage range of LA8040 is from 2.5V to 6V, and available in adjustable output voltage from 0.8V to VIN.

Key Features

  • of soft-start, current limit, thermal shutdown protection, short circuit protection, and over voltage protection are also included. The under voltage lockout prevents low input voltage start-up until it reaches the UVLO threshold voltage. It is available in the Exposed Pad SOP-8 (ESOP) package. Features l Continuous 2A Output Capability l 0.8V Reference Voltage l 2.5V to 6V Input Voltage Range l Adjustable Output from 0.8V to VIN l 1MHz Oscillation Frequency l 0.6mA Low Supply Current l 25uA Lo.

LA8040 1MHz, 5V/2A Synchronous Step-Down Converter General Description The LA8040 is a current mode, synchronous step-down DC-DC converter that is designed to meet 2A output current, and utilizes PWM control scheme that switches with 1MHz fixed frequency. The input voltage range of LA8040 is from 2.5V to 6V, and available in adjustable output voltage from 0.8V to VIN. The supply current is only 0.6mA during operation and under 25uA in shutdown. This device provides an enable function that can be controlled by external logic signal. It also provides excellent regulation during line or load transient due to the current mode operation. Other features of soft-start, current limit, thermal shutdown protection, short circuit protection, and over voltage protection are also included.
