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).
