High-Frequency 6A Sink Synchronous MOSFET Drivers with Protection Features
The ISL6615A is a high-speed MOSFET driver optimized to
drive upper and lower power N-Channel MOSFETs in a
synchronous rectified buck converter topology. This driver,
combined with an Intersil Digital or Analog multiphase PWM
controller, forms a complete high frequency and high
efficiency voltage regulator.
The ISL6615A drives both upper and lower gates over a
range of 4.5V to 13.2V. This drive-voltage provides the
flexibility necessary to optimize applications involving
trade-offs between gate charge and conduction losses.
The ISL6615A features 6A typical sink current for the
low-side gate driver, enhancing the lower MOSFET gate
hold-down capability during PHASE node rising edge,
preventing power loss caused by the self turn-on of the lower
MOSFET due to the high dV/dt of the switching node.
