ADP3611MNR2G-REEL
Description
Dual Bootstrapped, High Voltage MOSFET Driver with Output Disable
Manufacturer
ONSEMI [ON Semiconductor]
Datasheet
ADP3611
Product Preview
Dual Bootstrapped, High
Voltage MOSFET Driver
with Output Disable
N−channel switching MOSFETs in nonisolated synchronous buck
power converters used to power CPUs in portable computers. The
driver impedances have been chosen to provide optimum
performance in multiphase regulators at up to 25 A per phase. The
high−side driver can be bootstrapped relative to the switch node of
the buck converter and is designed to accommodate the high voltage
slew rate associated with floating high−side gate drivers. An internal
synchronous MOSFET is used to replace an external bootstrap
Schottky diode. This allows a larger high side gate voltage for
increased efficiency.
undervoltage lockout to hold the switches off until the driver has
sufficient voltage for proper operation, a crowbar input that turns on
the low−side MOSFET independently of the input signal state, and a
low−side MOSFET disable pin to provide higher efficiency at light
loads. The SD pin shuts off both the high−side and the low−side
MOSFETs to prevent rapid output capacitor discharge during system
shutdown.
temperature range of −10°C to 100°C and is available in a 10−lead
MSOP package and 8−lead DFN 2x2 mm package.
