ZVS Switching Regulators

PI3751-02

38 – 60V_IN, 240W Cool-Power ZVS Buck-Boost Regulator

Product Description

Features & Beneﬁts

The PI3751-02 is a high efﬁciency, wide input range DC-DC

ZVS Buck-Boost regulator. This high density module integrates

controller, power switches, and support components. The

integration of a high performance Zero-Voltage Switching

(ZVS) topology, within the PI3751-02, increases point of load

performance providing best in class power efﬁciency.

• Over 97.5% efﬁciency at 2.5MHz F_SW

• Wide input voltage range of 38 – 60V

• Wide output voltage range of 38 – 50V

• Up to 240W continuous output power / 512.5W peak

• Power density exceeding 1,389W/in³

• Fast transient response in VRM 13 applications

• Light load mode < 200mW no load power dissipation

• VTM™ compatibility mode

The PI3751-02 requires an externally applied 5V bias to the

VDR input, an external inductor, resistive divider and minimal

capacitors to form a complete DC-DC switching mode

buck-boost 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 PI3751-02

sustains high switchingfrequency up to the rated input voltage

withoutsacriﬁcing efﬁciency and supports large conversion ratios.

• High side current sense ampliﬁer

• User-conﬁgurable differential ampliﬁer

• Input / Output Over / Undervoltage Protection

• Temperature lockout protection

• Fast and slow current limits

• –40 to 125°C operating range (T_J)

Applications

• Factorized Power Solution

(when coupled with a VTM device)

• Computing, Communications, Processor, DDR Memory

• 48V to PoL Power Solutions
