4.1
MOSFET drivers are high-speed, high current devices
which are intended to source/sink high peak currents to
charge/discharge the gate capacitance of external
MOSFETs or IGBTs. In high frequency switching power
supplies, the PWM controller may not have the drive
capability to directly drive the power MOSFET. A
MOSFET driver like the MCP1415/16 family can be
used

The ability of a MOSFET driver to transition from a fully
off state to a fully on state are characterized by the

4.3
Careful layout and decoupling capacitors are required
when using power MOSFET drivers. Large current are
required to charge and discharge capacitive loads
quickly. For example, approximately 720 mA are
needed to charge a 1000 pF load with 18V in 25 ns.
To operate the MOSFET driver over a wide frequency
range with low supply impedance, a ceramic and low
ESR film capacitor is recommended to be placed in
parallel between the driver V
ESR film capacitor and a 0.1 µF ceramic capacitor
placed between pins 2 and 4 is required for reliable
operation. These capacitors should be placed close to
the driver to minimize circuit board parasitics and
provide a local source for the required current.
