-3300 pF in 10 ns (typical) Tri-State PWM Pin for Power Stage Shutdown Input Voltage Undervoltage Lockout Protection Space Saving Packages:
-8-Lead SOIC
-8-Lead 3x3 DFN The MCP14628 is a dual MOSFET gate driver
designed to optimally drive two N-Channel MOSFETs
arranged in a non-isolated synchronous buck converter
topology. With the capability to source 2A peaks
typically from both the high-side and low-side drives,
the MCP14628 is an ideal companion to buck controllers that lack integrated gate drivers. Additionally,
greater design flexibility is offered by allowing the gate
drivers to be placed close to the power MOSFETs. Applications High Efficient Synchronous DC/DC Buck

Converters Core Voltage Supplies for Microprocessors The MCP14628 features the capability to sink 3.5A
peak typically for the low-side gate drive. This allows
the MCP14628 the capability of holding off the low-side
power MOSFET during the rising edge of the PHASE
node. Internal adaptive cross conduction protection
circuitry is also used to mitigate both external power
MOSFETs from simultaneously conducting. …
