RAA220002

Dual Synchronous Rectified Buck MOSFET Driver

The RAA220002 is a dual high frequency MOSFET

driver designed to drive upper and lower power

N-channel MOSFETs in a synchronous rectified buck

converter topology.

Features

• Dual independent MOSFET driver suitable for

multi-phase DC/DC applications

• Dual MOSFET drives for synchronous rectified

bridge

The RAA220002’s upper and lower gates are both

driven to an externally applied voltage, which provides

the ability to optimize applications involving trade-offs

between gate charge and conduction losses.

• Advanced adaptive zero shoot-through protection

○ PHASE detection

An advanced adaptive shoot-through protection is

integrated to prevent both the upper and lower

MOSFETs from conducting simultaneously and to

minimize dead time. The RAA220002 has a 10kΩ

integrated high-side gate-to-source resistor to prevent

self turn-on due to high input bus dV/dt.

○ LGATE detection

○ Auto-zero of r

conduction offset effect

DS(ON)

• Low standby bias current

• 36V internal bootstrap switcher

• Bootstrap capacitor overcharging prevention

The RAA220002’s overvoltage protection feature is

• Integrated high-side gate-to-source resistor to

prevent self turn-on due to high input bus dV/dt

operational while V is below the POR threshold.

The PHASE node is connected to the gate of the

low-side MOSFET (LGATE) through a 30kΩ resistor,

limiting the output voltage of the converter close to the

gate threshold of the low-side MOSFET. This is

dependent on the current being shunted, which

provides some protection to the load if the upper

MOSFET(s) becomes shorted.

• Pre-POR overvoltage protection for start-up and

shutdown

• Power rail undervoltage protection

• Expandable bottom copper pad for enhanced heat

sinking

• Thin Dual Flat No-lead (TDFN) package

Applications

• Near chip-scale package footprint; improves PCB

efficiency and thinner in profile

• High light-load efficiency voltage regulators

• Core regulators for advanced microprocessors

• High current DC/DC converters

• Pb-free (RoHS compliant)
