Automotive PWM DC/DC Voltage Controller
ISL78210
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 events in conjunction with external loop
compensation produces superior transient response. For
maximum efficiency, the converter automatically enters
diode-emulation mode (DEM) during light-load conditions such as
system standby.
