توضیحات
NCP3420DR يک ايسي درايور ماسفت ميباشد.ماسفت ها و يا IGBT ها در گيت خود يک خازن دارند که با شارژ شدن اين خازن ماسفت يا IGBT روشن و با دشارژ شدن خازن، خاموش مي شوند. اين خازن براي آنکه در زمان کوتاهي شارژ و دشارژ شود نيازمند يک جريان مشخصي است که بايد در کمترين زمان خازن را شارژ کند تا ماسفت بدون تاخير روشن شود.

Description
The NCP3420 is a single Phase 12 V MOSFET gate driver
optimized to drive the gates of both high-side and low-side power
MOSFETs in a synchronous buck converter. The high-side and
low-side driver is capable of driving a 3000 pF load with a 30 ns
propagation delay and a 20 ns transition time.
With a wide operating voltage range, high or low side MOSFET
gate drive voltage can be optimized for the best efficiency. Internal
adaptive nonoverlap circuitry further reduces switching losses by
preventing simultaneous conduction of both MOSFETs.
The floating top driver design can accommodate VBST voltages as
high as 35 V, with transient voltages as high as 40 V. Both gate outputs
can be driven low by applying a low logic level to the Output Disable
(OD) pin. An Undervoltage Lockout function ensures that both driver
outputs are low when the supply voltage is low, and a Thermal
Shutdown function provides the IC with overtemperature protection.
Features
• Thermal Shutdown for System Protection
• Internal Pulldown Resistor Suppresses Transient Turn On of Either
MOSFET
• Anti Cross-Conduction Protection Circuitry
• One Input Signal Controls Both the Upper and Lower Gate Outputs
• Output Disable Control Turns Off Both MOSFETs
• Complies with VRM10.x and VRM11.x Specifications
• Undervoltage Lockout
• Thermally Enhanced Package Available
• These are Pb?Free Devices
