Product Overview
DC2493A is a demonstration circuit featuring the LTC®3892EUH-2, high output voltage capable, high-efficiency synchronous PolyPhase® buck converter. The output voltage of the DC2493A is set to 12V, however, the output voltage can go as high as 55V, with certain modifications. The DC2493A supports three operation modes: fixed-frequency modulation, pulse-skipping mode and Burst Mode® operation. Fixed-frequency mode of operation reduces output voltage ripple, and yields a low noise switching spectrum. Burst Mode operation employs a variable frequency switching algorithm that minimizes the input quiescent current and improves efficiency at light loads. The DC2493A consumes less than 5µA of quiescent current during shutdown and it consumes less than 1mA at a no load condition in Burst Mode operation. The DC2493A has a standard operating frequency of 150KHz, but can be adjusted to frequencies as high as 900KHz.
- DC2493 is a dual phase step-down converter
- Designed to be easily transformed to a 4- or 6-phase system by combining 2 or 3 DC2493A boards
- DC2493A has a wide input voltage range from 16V to 55V
- Capable of delivering up to 30A of output current
- 12V ±2% output voltage VOUT regulation at VIN = 16V to 55V
- 150KHz preset operating frequency at R-PRG = 31.6Kohm
- External clock sync frequency range from 75 to 850KHz
- Typical output ripple VOUT is < 35mVP-P at VIN = 36V, IOUT = 15A (20MHz BW)
- Quiescent current at shut-down is < 7µA at VIN = 16V to 55V
- Input current at no load is < 100µA at VIN = 16V to 55V
