PI3741-01 Datasheet | VICOR

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 (Si P). Integrating controller, power switches, support ponents 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 plete DC-DC switching mode buck-boost regulator. Device PI3741-00-LGIZ PI3741-01-LGIZ Output Voltage Set Range 24V - 36V 48V - 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 ponents, 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 115°C operating range (TJ) - Excellent light-load efficiency Applications - Tele, Networking, Lighting - puting, munications, Industrial - Renewable Energy Systems Typical Application Package Information - 10 x 14 x 2.56mm LGA Si...
