ISL78210
Automotive PWM DC/DC Voltage Controller
The ISL78210 IC is a Single-Phase Synchronous-Buck PWM voltage controller featuring Intersil’s Robust Ripple
Regulator (R3™) Technology. The ISL78210 provides a low cost solution for compact high performance applications. The wide 3.3V to 25V input voltage range is ideal for systems that run on battery or AC adapter power sources. Resistor programmed output voltage setpoint and capacitor programmed soft-start delay allow for fast and easy implementation. Robust integrated MOSFET drivers and
Schottky bootstrap diode reduce the implementation area and lower component cost.
Intersil’s R3 Technology™ combines the best features of both fixed-frequency and hysteretic PWM control. The PWM frequency is 300kHz during static operation, becoming variable during changes in load, setpoint voltage, and input voltage when changing between battery and AC adapter power. The modulators ability to change the PWM switching frequency during these eve...
