DATASHEET ISL78233, ISL78234 3A and 4A Compact Synchronous Buck Regulators FN8359 Rev.11.01 Jun 16, 2022 The ISL78233 and ISL78234 are highly efficient, monolithic, synchronous step-down DC/DC converters that can deliver 3A (ISL78233), or 4A (ISL78234) of continuous output current from a 2.7V to 5.5V input supply. 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 component count. The 100% duty-cycle operation allows less than 200mV dropout voltage at 4A output current.
