PI3741-00

ZVS Regulators PI3741-0x 21V to 60VIN, 150W ZVS Buck-Boost Regulator Product Description 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. The PI3741-0x requires an external inductor, resistive divider and minimal capacitors to form a complete DC-DC switching mode buck-boost regulator. Device PI3741-00-LGIZ PI3741-01-LGIZ Output Voltage Set Range 24V 21 – 36V 48V 36 – 54V 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. Features & Benefits 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 Input Over/Undervoltage Lockout (OVLO/UVLO) Output Overvoltage Protection (OVP) Overtemperature Protection (OTP) Fast and slow current limits –40 to...
