Intersil announced a pair of multiple-output standard buck ICs that integrate critical power management functions to suit a variety of point-of-load (POL) applicationssuch as 5V FPGA/CPLD and DSP power supplies, 12V telecom/datacom power supplies and 24V battery-powered handhelds. The ISL8501 and ISL8510 feature a 5V fixed input voltage capability and variable input voltage ranges up to 25V. The ISL8501 is a triple output controller with two 500 mA LDOs and a 1A standard PWM regulator with integrated high-side power MOSFET, while the ISL8510 is a dual output device with a single 500 mA LDO and a 1A standard PWM regulator. Both devices integrate two PGOOD (Power OK) outputs for the PWM and the LDOs, along with dedicated ENABLE inputs, eliminating the need for a separate sequencer/supervisor. The output voltage of the LDO(s) is fully adjustable from 0.6V to 4.2V and the PWM regulator’s output voltage is adjustable from 0.6V to 20V.
