ZVS Switching Regulators

PI3741-0x

21V to 60V_IN, 150W, Cool-Power ZVS Buck-Boost Regulator

Product Description

Features & Beneﬁts

The PI3741-0x series is a high efﬁciency, wide range DC-DC ZVS

Buck-Boost Regulator with two output range conﬁgurations that

utilize the same high density System-in-Package (SiP). Integrating

controller, power switches, support components and a high

performance Zero-Voltage Switching (ZVS) topology within the

PI3741-0x increases point of load performance while providing

best in class power efﬁciency.

• Up to 97% efﬁciency

• 150W of continuous output power

(for speciﬁc conditions)

• Fast transient response

• Parallel capable with single wire current sharing

• External frequency synchronization / interleaving

• High Side Current Sense Ampliﬁer

• General Purpose Ampliﬁer

The PI3741-0x requires an external inductor, resistive divider and

minimal capacitors to form a complete DC-DC switching mode

buck-boost regulator.

Output Voltage

Device

• Input Over/Undervoltage Lockout (OVLO/UVLO)

• Output Overvoltage Protection (OVP)

• Over Temperature Protection (OTP)

• Fast and slow current limits

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 fast

dynamic response to line and load transients.

• -40°C to 115°C operating range (T_J)

• Excellent light load efﬁciency

Applications

• Telecom, Networking, Lighting

• Computing, Communications, Industrial

• Renewable Energy Systems
