ZVS Regulators PI3741-0x 21V to 60V , 150W ZVS Buck-Boost Regulator IN Product Description Features & Benefits The PI3741-0x series is a high efficiency, wide range DC-DC ZVS Up to 97% efficiency Buck-Boost Regulator with two output range configurations 150W of continuous output power that utilize the same high-density System-in-Package (SiP). (for specific conditions) Integrating controller, power switches, support components and a high-performance Zero-Voltage Switching (ZVS) topology Fast transient response within the PI3741-0x increases point-of-load performance while providing best-in-class power efficiency. Parallel capable with single-wire current sharing The PI3741-0x requires an external inductor, resistive divider and External frequency synchronization / interleaving minimal capacitors to form a complete DC-DC switching mode High-Side Current Sense Amplifier buck-boost regulator. General Purpose Amplifier Output Voltage Input Over/Undervoltage Lockout (OVLO/UVLO) Device Set Range Output Overvoltage Protection (OVP) PI3741-00-LGIZ 24V 21 36V Overtemperature Protection (OTP) 48V 36 54V PI3741-01-LGIZ Fast and slow current limits The ZVS architecture also enables high-frequency operation while 40 to 115C operating range (T ) J minimizing switching losses and maximizing efficiency. The high switching frequency operation reduces the size of the external Excellent light-load efficiency filtering components, improves power density, and enables fast dynamic response to line and load transients.
