Product Details

The MAX15022 evaluation kit (EV kit) circuit demonstrates the MAX15022 IC, which integrates two high-performance PWM switching step-down regulators and two low-dropout (LDO) controllers. Each controller and regulator features independent enable controls for power-up sequence operation. The EV kit is designed to operate from a single 4.5V to 5.5V DC power supply.

The synchronous step-down outputs provide 3.3V/4A and 1.5V/2A, and can be configured for power-up sequencing or tracking operation. The converter switching frequency is set to 2MHz and operates 180° out-of-phase, reducing input voltage ripple and total RMS input ripple current. The LDO outputs provide 2.5V and 1.2V, at up to 500mA each. Each LDO controller is powered from either the input power source or one of the regulator outputs.
