DrMOS Power Module
General Description
AOZ5507QI is a high efficiency synchronous buck power
stage module consisting of two asymmetrical MOSFETs
and an integrated driver. The MOSFETs are individually
optimized for operation in the synchronous buck
configuration. The High-Side MOSFET is optimized to
achieve low capacitance and gate charge for fast
switching with low duty cycle operation. The Low-Side
MOSFET has ultra-low ON resistance to minimize
conduction loss.
AOZ5507QI uses a PWM input for accurate control of the
power MOSFETs switching activities, is compatible with
5V (CMOS) logic and supports Tri-State PWM.
A number of features are provided making the
AOZ5507QI a highly versatile power module. The
bootstrap switch is integrated in the driver. The Low-Side
MOSFET can be driven into diode emulation mode to
provide asynchronous operation and improve light-load
performance. The pin-out is also optimized for low
parasitics, keeping their effects to a minimum.

Pin Function
Continuous conduction mode of operation is allowed when FCCM = High.
Discontinuous mode is allowed and diode emulation mode is active when FCCM = Low.
High impedance on the input of FCCM will shut down both High-Side and Low-Side MOSFETs.
5V Bias for Internal Logic Blocks. Ensure to position a 1µF MLCC directly between VCC and
PGND (Pin 20).
Internally connected to PGND paddle. It can be left floating (no connect) or tied to PGND.
High-Side MOSFET Gate Driver supply rail. Connect a 100nF ceramic capacitor between
BOOT and the PHASE (Pin 5).
This pin is dedicated for bootstrap capacitor AC return path connection from BOOT (Pin 4).
Power stage High Voltage Input (Drain connection of High-Side MOSFET).
PGND
Power Ground pin for power stage (Source connection of Low-Side MOSFET).

PWM
Switching node connected to the Source of High-Side MOSFET and the Drain of Low-Side
MOSFET. These pins are used for Zero Cross Detection and Anti-Overlap Control as well as
main inductor terminal.
Low-Side MOSFET Gate connection. This is for test purposes only.
Power Ground pin for High-Side and Low-Side MOSFET Gate Drivers. Ensure to connect 1µF
directly between PGND and PVCC (Pin 21).
5V Power Rail for High-Side and Low-Side MOSFET Drivers. Ensure to position a 1µF MLCC
directly between PVCC and PGND (Pin 20).
PWM input signal from the controller IC. This input is compatible with 5V and Tri-State logic
levels.
