PI33XX-X0

8V to 36Vin Cool-Power ZVS Buck Regulator Family

Description

Features

The PI33XX 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 series,

increases point of load performance providing best in

class power efficiency. The PI33XX requires only an

external inductor and minimal capacitors to form a

complete DC-DC switching mode buck regulator.

 High Efficiency ZVS-Buck Topology

 Wide input voltage range of 8V to 36V

 Very-Fast transient response

 High accuracy pre-trimmed output voltage

 User adjustable soft-start & tracking

 Power-up into pre-biased load (select versions)

 Parallel capable with single wire current sharing

 Input Over/Under Voltage Lockout (OVLO/UVLO)

 Output Overvoltage Protection (OVP)

 Over Temperature Protection (OTP)

 Fast and slow current limits

Applications

 High efficiency systems

 Computing, Communications, Industrial,

Automotive Equipment

Table 1 - PI33XX-X0 Portfolio.

 High voltage battery operation

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 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.
