ISL78235R5668
ISL78235R5668 is Automotive 5A Synchronous Buck Regulator manufactured by Renesas.
Automotive 5A Synchronous Buck Regulator
The ISL78235R5668 is a highly efficient, monolithic, synchronous step-down DC/DC converter that can deliver 5A continuous and up to 8A pulsed output current from a 2.7V to 5.5V input supply. The device uses peak current mode control architecture to achieve very low duty cycle operation at high frequency with fast transient response and excellent loop stability.
The ISL78235R5668 integrates a low ON-resistance P-channel (35mΩ, typical) high-side FET and N-channel (11mΩ, typical) low-side FET to maximize efficiency and minimize external ponent count. The 100% duty cycle operation allows less than 250m V dropout voltage at 5A output current. The operating frequency of the Pulse-Width Modulator (PWM) is adjustable from 500k Hz to 4MHz. The default switching frequency of 2MHz is set by connecting the FS pin high.
The ISL78235R5668 can be configured for discontinuous (PFM) or forced continuous (PWM) operation at light load. Forced...
