Analog Devices’ LTC7804 offers low Iq, small solution size, and PassThru™ operation for up to 99.9% efficiency
ADI’s LTC7804 is a low IQ, 3 MHz PassThru operation capable synchronous boost DC/DC switching regulator controller that operates up to a 40 V input voltage.
Its low quiescent current extends operating runtime in battery-powered systems. Spread spectrum frequency operation helps reduce radiated and conducted EMI peaks, and up to 3 MHz switching reduces the solution size, ideal for a broad range of applications and markets.
Features:
- Synchronous operation for reduced power dissipation
- PassThru operation/100% duty cycle capability for synchronous MOSFET
- Wide VIN range: 4.5 V to 40 V, operates down to 1 V after start-up
- Output voltage up to 40 V
- Low operating IQ: 14 μA
- Spread spectrum operation
- Selectable fixed frequency (100 kHz to 3 MHz)
- AEC-Q100
