RT9607/A

Dual Channel Synchronous-Rectified Buck MOSFET Driver

General Description

Features

^zDrives Four N-MOSFETs

The RT9607/A is a dual power channel MOSFET driver

specifically designed to drive four powerN-MOSFETs in a

synchronous-rectified buck converter topology. These

drivers combined with RichTek’ s series of Multi-Phase

Buck PWM controllers provide a complete core voltage

regulator solution for advanced microprocessors.

^zAdaptive Shoot-Through Protection

^zPropagation Delay 40ns

^zSupport High Switching Frequency

^zFast Output Rise Time

^z5V to 12V Gate-Drive Voltages for Optimal Efficiency

^zTri-State Input for Bridge Shutdown

^zSupply Under-Voltage Protection

^zRoHS Compliant and 100% Lead (Pb)-Free

The RT9607/A can provide flexible gate driving for both

high side and low side drivers. This gives more flexibility

of MOSFET selection.

The output drivers of the part are capble to driver a 3nF

load in 30/40ns rising/falling time with fast propagation

delay from input transition to the gate of the power

MOSFET. This device implements bootstrapping on the

upper gates with only a single external capacitor required

for each power channel. This reduces implementation

complexity and allows the use of higher performance, cost

effective,N-MOSFETs.Adaptive shoot-through protect-ion

is integrated to prevent both MOSFETs from conducting

simultaneously.

Applications

z Core Voltage Supplies for motherboard/desktop PC

microprocessor core power

z High Frequency Low ProfileDC-DC Converters

z High Current Low VoltageDC-DC Converters

Ordering Information

RT9607/A

Package Type

QV : VQFN-16L 3x3 (V-Type)

S : SOP-14

The RT9607/A can detect high side MOSFET drain-to-

source electrical short at power on and pull the 12V power

by low side MOS and cause power supply to go into over

current shutdown to prevent damage of CPU.

Lead Plating System

P : Pb Free

G : Green (Halogen Free and Pb Free)

Short Dead Time

Long Dead Time

RT9607 has longer UGATE/LGATE dead time which can

drive the MOSFETs with large gate RC value, avoiding

the shoot-through phenomenon. RT9607A is targeted to

drive small gate RC value MOSFETs and performs better

efficiency.

Note :

Richtek products are :

` RoHS compliant and compatible with the current require-

ments of IPC/JEDEC J-STD-020.

` Suitable for use in SnPb or Pb-free soldering processes.

Marking Information

For marking information, contact our sales representative

directly or through a Richtek distributor located in your

area.
