Vishay Siliconix
30 A VRPower® Integrated Power Stage
DESCRIPTION
The SiC534 is an integrated power stage solution optimized
for synchronous buck applications to offer high current, high
efficiency, and high power density performance. Packaged
in Vishay’s proprietary 4.5 mm x 3.5 mm MLP package,
SiC534 enables voltage regulator designs to deliver up to
30 A continuous current per phase.
The internal power MOSFETs utilize Vishay’s
state-of-the-art Gen IV TrenchFET technology that delivers
industry benchmark performance to significantly reduce
switching and conduction losses.
The SiC534 incorporates an advanced MOSFET gate driver
IC that features high current driving capability, adaptive
dead-time control, an integrated bootstrap Schottky diode,
and zero current detection to improve light load efficiency.
The driver is also compatible with a wide range of PWM
controllers, supports tri-state PWM, and 5 V PWM logic.
A user selectable diode emulation mode (ZCD_EN#) is
included to improve the light load performance. The device
also supports PS4 mode to reduce power consumption
when system operates in standby state.

FUNCTION
The ZCD_EN# pin enables or disables Diode Emulation. When ZCD_EN# is LOW, diode
emulation is allowed. When ZCD_EN# is HIGH, continuous conduction mode is forced.
ZCD_EN# can also be put in a high impedance mode by floating the pin. If both ZCD_EN#
and PWM are floating, the device shuts down and consumes typically 3 μA (9 μA max.)
current.

Analog ground for the driver IC
This pin can be either left floating or connected to CGND.
Internally it is either connected to GND or not internally
connected depending on manufacturing location.
