High Frequency, Low IQ Synchronous Step-Down Controller

Details

TopologieAbwärtswandler
Eingangsspannung5-38 V
Ausgang 13.3 V / 20 A

Beschreibung

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.

Eigenschaften

  • 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).
