Regulated DC/DC converter ZVS

non-isolatedSIPindustrial

Product overview
PI3423-00-LGIZ is a non‑isolated ZVS (Zero-Voltage Switching) buck DC-DC regulator from the PI34xx family. Optimized for 12 Vin operation, it targets high-efficiency, high-density power designs and rapid evaluation/development. The device is supplied in a compact 10 x 14 LGA-SIP package (14.0 x 10.0 x 2.56 mm).
