HIP2105, HIP2106A
Low Voltage Driver for Synchronous Rectification
The HIP2105 and HIP2106A are high frequency
MOSFET drivers optimized to drive two N-channel
power MOSFETs in a synchronous buck converter
topology. The HIP2105 has HI/LI inputs and the
HIP2106A has a single PWM input. Both these drivers,
combined with Renesas multi-phase buck PWM
controllers, form a complete single-stage core-voltage
regulator solution with high-efficiency performance at
high switching frequency for advanced microprocessors.
The HIP2105 and HIP2106A are biased by a single low
voltage supply (5V), minimizing driver switching losses
in high MOSFET gate capacitance and high switching
frequency applications. Each driver is capable of driving
a 3nF load with less than 15ns rise/fall time.
Bootstrapping of the upper gate driver is implemented
using an internal low forward voltage drop diode,
reducing implementation cost, complexity, and allowing
the use of higher performance, cost effective N-channel
MOSFETs. Adaptive shoot-through protection on the
HIP2106A is integrated to prevent both MOSFETs from
conducting simultaneously.
The HIP2105 and HIP2106A feature a 4A typical sink
current for the lower gate driver, enhancing the lower
MOSFET gate hold-down capability during PHASE
node rising edge, preventing power loss caused by the
self turn-on of the lower MOSFET due to the high dV/dt
of the switching node.
The HIP2106A also features an input that recognizes a
high-impedance state, working together with Renesas
multi-phase 3.3V or 5V PWM controllers to prevent
negative transients on the controlled output voltage when
operation is suspended. This feature eliminates the need
for the Schottky diode that may be used in a power system
to protect the load from negative output voltage damage.
