DC2834A

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. The 500KHz constant switching frequency operation results in a small and efficient circuit. The DC2834A has a small circuit footprint, is a high performance and high density solution for telecom, automotive and Power over Ethernet applications.

• 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 or low ripple Burst Mode® operation at light loads
• Synchronization with external clock
• DC2834A supports RSENSE or inductor DCR current sensing (optional)
