The RT9602 is a, twin power channel MOSFET driver
specifically designed to drive four power N-Channel
MOSFETs in a synchronous-rectified buck converter
topology. These drivers combined with a
RT9237/RT9241 series of Multi-Phase Buck PWM
controller provide a complete core voltage regulator
solution for advanced microprocessors.
The RT9602 can provide flexible gate driving for both
high side and low side drivers. This gives more
flexibility of MOSFET selection.
The output drivers in the RT9602 have the capability
to drive a 3000pF load with a 40ns propagation delay
and 80ns transition time. 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, NChannel
MOSFETs. Adaptive shoot-through
protection is integrated to prevent both MOSFETs
from conducting simultaneously.
The RT9602 can detect high side MOSFET drain-tosource
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.
