APPLICATION CIRCUIT
ORDER INFORMATION
DESCRIPTION
The IR3519 is extended voltage range high-speed gate
driver optimized for switching power supply
applications. Performance is achieved by 7V/2A gate
source and 5-A sink drive capability and is capable of
operating at frequencies of up to 2MHz.
The 0.4- Ω impedance of the lower gate driver holds the
gate of the Synchronous MOSFET below its threshold
to prevent shoot-through current during high dv/dt
phase node transitions.
The IR3519 includes a two-way enable/under voltage
power good signal. Systems without 3-state featured
controllers can use the EN/UV input/output to hold both
outputs low during converter shut down.
