PI3740-00

ZVS Regulators PI3740-00 8V – 60VIN , 10V – 50VOUT , 50 – 140W ZVS Buck-Boost Regulator Product Description The PI3740-00 is a high-efficiency, wide input and output range DC-DC ZVS Buck-Boost Regulator. This high-density System‑in‑Package (SiP) integrates controller, power switches, and support components. The integration of a high-performance Zero‑Voltage Switching (ZVS) topology within the PI3740-00 increases point-of-load performance, providing best-in-class power efficiency. The PI3740-00 requires an external inductor, resistive divider and minimal capacitors to form a complete DC-DC switching mode buck-boost regulator. Device PI3740-00 Output Voltage Set Range 12V 10 – 50V 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. Typical Application Features & Benefits Up to 96% efficiency 50 – 140W continuous output power Parallel-capable with single-wire current sharing External frequency synchronization / interleaving High-side current sense amplifier General-purpose amplifier Lighting / constant current mode (LGH) Input over / undervoltage lockout (OVLO / UVLO) Output overvoltage protection (OVP) Overtemperature protection (OTP) Fast and slow current limits –40 to 115°C operating range (TJ), -L...
