Overview
| Topology | Boost Converter |
| Input voltage | 6-24 V |
| Output 1 | 24 V / 3 A |
Description
Demonstration circuit DC2846A is a DC/DC synchronous boost converter featuring the LTC®7804 (MSE package), a spread spectrum or constant frequency current mode synchronous boost controller. The DC2846A generates a 24V output voltage and provides up to 6A of output current.
Features
- Wide input voltage range: from 6V to 24V
- Relatively high output power, up to 150W
- Extremely low quiescent current, it’s 15μA at sleep mode and as low as 1μA at shutdown
- Onboard low power bias supply
- Ability to select spread spectrum or fixed frequency
- Pulse-skipping mode, forced continuous operation or low ripple Burst Mode® operation at light loads
- Synchronization with external clock
