PI33XX-X1
8V to 36Vin, 15A Cool-Power ZVS Buck Regulator
Description
The PI33XX-X1 is a family of high efficiency, wide
input range DC-DC ZVS-Buck regulators integrating
controller, power switches, and support components
all within a high density System-in-Package (SiP). The
integration of a high performance Zero-Voltage
Switching (ZVS) topology, within the PI33XX-X1 series,
increases point of load performance providing best in
class power efficiency. The PI33XX-X1 requires only
an external inductor and minimal capacitors to form a
complete DC-DC switching mode buck regulator.

The ZVS architecture also enables high frequency
operation while minimizing switching losses and
maximizing efficiency. The high switching frequency
operation reduces the size of the external filtering
components, improves power density, and enables
very fast dynamic response to line and load
transients. The PI33XX-X1 series sustains high
switching frequency all the way up to the rated input
voltage without sacrificing efficiency and, with its
20ns minimum on-time, supports large step down
conversions up to 36Vin.
Features

Description
Signal ground: Internal logic ground for EA, TRK, SYNCI, SYNCO, ADJ and I2C (options)
communication returns. SGND and PGND are star connected within the regulator package.
Power ground: VIN and VOUT power returns
Input voltage: and sense for UVLO, OVLO and feed forward ramp
Output voltage: and sense for power switches and feed-forward ramp
Switching node: and ZVS sense for power switches
Parallel Good: Used for parallel timing management intended for lead regulator.
Error amp output: External connection for additional compensation and current sharing.
Enable Input: Regulator enable control. Asserted high or left floating – regulator enabled;
Asserted low, regulator output disabled. Polarity is programmable via I2C interface.
Remote Sense: High side connection. Connect to output regulation point.
Adjust input: An external resistor may be connected between ADJ pin and SGND or VOUT to trim
the output voltage up or down.
Soft-start and track input: An external capacitor may be connected between TRK pin and SGND
to decrease the rate of rise during soft-start.
No Connect: Leave pins floating.
Synchronization output: Outputs a low signal for ½ of the minimum period for synchronization of
other converters.
Synchronization input: Synchronize to the falling edge of external clock frequency. SYNCI is a high
impedance digital input node and should always be connected to SGND when not in use.
Data Line: Connect to SGND for PI33XX-10 and -11. For use with PI33XX-20 and -21 only.
Clock Line: Connect to SGND for PI33XX-01. For use with PI33XX-21 only.
Tri-state Address : No connect for PI33XX-01. For use with PI33XX-21 only.
Tri-state Address : No connect for PI33XX-01. For use with PI33XX-21 only.
