Switching Controllers

Analog Devices offers a range of synchronous and asynchronous switching controllers to provide efficient voltage rails down to voltages as low as 0.6 V and up to 50 A. Switching controllers offer flexibility to set output current level and limits ranging from zero to > 5 A for asynchronous designs and > 20 A channel for synchronous designs. Controller based switching regulators provide highest efficiency and performance that can be tailored to the application's requirements. Available features include single and dual channels, enable, softstart, UVLO, current limit, margining, tracking, frequency synchronization, 3 V to 24 V input voltage range, power good flag, and output accuracy to 0.5% accuracy 25°C.

ADP1877- Dual Output Synchronous Buck PWM Controller With Tracking

ADP1877: Dual Output Synchronous Buck PWM Controller With Tracking

The ADP1877 is a Flexmode® (proprietary architecture of Analog Devices, Inc.), dual-channel, step-down switching controller with integrated drivers that drive N-channel synchronous power MOSFETs. The two PWM outputs are phase shifted 180°, which reduces the input RMS current, thus minimizing required input capacitance.

The boost diodes are built into the ADP1877, thus lowering the overall More
