The ISL6615 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 ISL6615 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 ISL6615 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.
