Analog Devices Inc. DC3189A Demonstration Circuit

Analog Devices Inc. DC3189A Demonstration Circuit showcases the LTM4712, a high-efficiency buck-boost μModule® regulator. Analog Devices Inc. LTM4712 delivers up to 12A in buck and buck-boost modes, 6A under 12VIN and 24VOUT. The DC3189A demo board uses constant-current mode (CCM) for precise regulation, even with varying loads. Optimized at 400kHz, the DC3189A uses peak-current mode control in the LTM4712, operating in continuous current mode by default. The device can switch to pulse-skipping mode for enhanced efficiency at lighter loads.
