HIP2106A

Low Voltage Driver for Synchronous Rectification

FN8999

Rev.0.00

Jan 18, 2018

The HIP2106A is a high frequency MOSFET driver

optimized to drive two N-channel power MOSFETs in a

synchronous buck converter topology. This driver,

combined with Renesas multi-phase buck PWM

controllers, forms a complete single-stage core-voltage

regulator solution with high-efficiency performance at

high switching frequency for advanced microprocessors.

The HIP2106A is 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 10ns rise/fall time. Bootstrapping of the

upper gate driver is implemented using an internal low

forward drop diode, reducing implementation cost,

complexity, and allowing the use of higher performance,

cost effective N-channel MOSFETs. Adaptive

shoot-through protection is integrated to prevent both

MOSFETs from conducting simultaneously.

The HIP2106A features 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.
