Single-output PWM controllers allow a lower BOM cost by integrating the boot diode, the overcurrent protection, and the MOSFET drivers onto a single chip.
Intersil's ISL6545 and ISL6545A single-output PWM (pulsewidth modulation) controllers allow a lower BOM cost by integrating the boot diode, the overcurrent protection, and the MOSFET drivers onto a single chip, reducing the number of external components and saving onboard space The devices' overcurrent function protects the controllers from a shorted output by using the lower MOSFET's on-resistance to monitor the current, enhancing the efficiency of the controllers and reducing cost by eliminating the current-sensing resistor
