The ISL8033 and ISL8036 are 5 V, 3 A dual step-down regulators with integrated power MOSFETs. Similar to the previous devices, the ISL8033 and ISL8036 integrate selectable PFM/PWM mode operation to enhance light load conversion efficiency, synchronization to external clock (up to 4 MHz), independent power-good and enable for complete start-up and monitoring control, and internal current mode compensation. The two channels in the ISL8033/36 switch 180° out-of-phase in order to reduce the input filter requirements. The ISL8033 provides the customer with the ability to program the output current capability for each channel via a configurable OCP threshold. The maximum continuous load capability will still be 3 A per channel. The ISL8036, on the other hand, provides the additional feature of current sharing between the two channels and between multiple ICs to support greater than 3 A load requirements.
