The ISL6520EVAL1 evaluation board highlights the operation of the ISL6520A synchronous buck PWM controller in an embedded application.
The evaluation board is populated with the ISL6520A controller IC and is flexible enough to allow for reference designs with 5A, 10A and 15A output currents at a fixed output voltage of 3.3V. A simple resistor change allows the output to go as low as 0.8V to as high as the input voltage. This flexibility allows a power supply designer to easily modify an existing design to suit almost any relevant application. The ISL6520EVAL1 DC/DC converter demo boards are customized to provide up to 15A of current at a fixed output voltage.
Designed to drive N-channel MOSFETs in a synchronous buck topology, the ISL6520A integrates the control, output adjustment, monitoring, and protection functions into a single 8-Lead package. The ISL6520A provides simple, single feedback loop, voltage-mode control with fast transient response. The output voltage can be precisely regulated to as low as 0.8V, with a maximum tolerance of ±1.5% over-temperature and line voltage variations. A fixed frequency oscillator reduces design complexity, while balancing typical application cost and efficiency.
