ISL78233 Description
The devices use current mode control architecture to deliver a very low duty cycle operation at high frequency with fast transient response and excellent loop stability. The ISL78233 and ISL78234 integrate a very low ON-resistance P-channel (35mΩ) high-side FET and N-channel (11mΩ) low-side FET to maximize efficiency and minimize external ponent count. The 100% duty-cycle operation allows less than 200mV dropout...
