reference designLTC7803 | Demoboard DC2834A

Overview

Topology	Buck Converter
Input voltage	5-38 V
Output 1	3.3 V / 20 A

Description

Demonstration circuit DC2834A is a DC/DC synchronous step-down converter featuring the LTC®7803 (MSE package), a spread spectrum or constant frequency current mode synchronous step-down controller. The DC2834A generates a 3.3V of output voltage.

Features

Wide input voltage range: from 5V to 38V
High load current, up to 20A
Extremely low quiescent current: 15μA in sleep mode and as low as 1μA at shutdown
Ability to select spread spectrum or fixed frequency
Selectable pulse-skipping, forced continuous operation or low ripple Burst Mode® operation at light loads
Synchronization with external clock
The DC2834A supports RSENSE or inductor DCR cur¬rent sensing (optional).
