DC2922A-A/DC2922A-B Demo Circuits for LTC7802

Analog Devices Inc. DC2922A-A/DC2922A-B Demonstration Circuits are dual step-down DC/DC converters featuring the LTC®7802 or LTC7802-3.3 PWM controllers. Both controller IC’s used on these demo boards are 40V Low IQ, Dual, 2-Phase Synchronous Step-Down Controllers with Spread Spectrum. And both demo boards operate over a 5V to 36V input voltage range and provide 3.3V at 20A and 5V at 15A outputs. The DC2922A-A uses the LTC7802 and has a resistor divider network to set the 3.3V output. The DC2922A-B uses the LTC7802-3.3 and has a fixed 3.3V output without requiring the resistor divider network.
