DESCRIPTION
The SiC46x is a family of wide input voltage high efficiency
synchronous buck regulators with integrated high side and
low side power MOSFETs. Its power stage is capable of
supplying high continuous current at up to 2 MHz switching
frequency. This regulator produces an adjustable output
voltage down to 0.8 V from 4.5 V to 60 V input rail
to accommodate a variety of applications, including
computing, consumer electronics, telecom, and industrial.
SiC46x’s architecture delivers ultrafast transient response
with minimum output capacitance and tight ripple regulation
at very light load. The device is internally compensated and
is stable with any capacitor. No external ESR network is
required for loop stability purpose. The device also
incorporates a power saving scheme that significantly
increases light load efficiency. The regulator integrates a full
protection feature set, including over current protection
(OCP), output overvoltage protection (OVP), short circuit
protection (SCP), output undervoltage protection (UVP) and
thermal shutdown (OTP). It also has UVLO for input rail and
a user programmable soft start.
The SiC46x family is available in 2 A, 4 A, 6 A, 10 A pin
compatible 5 mm by 5 mm lead (Pb)-free power enhanced
MLP55-27L package.

DESCRIPTION
Supply voltage for internal regulators VDD and VDRV. This pin should be tied to VIN, but can also be
connected to a lower supply voltage (> 5 V) to reduce losses in the internal linear regulators
Open-drain power good indicator - high impedance indicates power is good. An external pull-up
resistor is required
Enable pin. Tie high / low to enable / disable the IC accordingly. This is a high voltage compatible pin,
can be tied to 60 V
High side driver bootstrap voltage
Return path of high side gate driver
Power stage input voltage. Drain of high side MOSFET
Power ground
Power stage switch node
Low side MOSFET gate signal
Supply voltage for internal gate driver. When using the internal LDO as a bias power supply, VDRV is
the LDO output. Connect a 4.7 μF decoupling capacitor to PGND
No connection internally
Set the soft start ramp by connecting a capacitor to AGND. An internal current source will charge the
capacitor
Output voltage sense point for internal ripple injection components
Feedback input for switching regulator used to program the output voltage - connect to an external
resistor divider from VOUT to AGND
Analog ground
Set the on-time by connecting a resistor to AGND
Set the current limit by connecting ILIMIT pin to AGND, float or VDD
Bias supply for the IC. VDD is an LDO output, connect a 1 μF decoupling capacitor to AGND
Set various operation modes by connecting a resistor to AGND. See specification table for details
