Product
PI3305-00-LGIZ — non-isolated ZVS buck regulator module from the PI33 series by Vicor.

Summary
Compact non-isolated ZVS buck regulator module. Nominal input voltage 24 V, nominal output 15 V, maximum output current 8 A. Package: 10 x 14 LGA‑SIP (14.0 x 10.0 x 2.56 mm). Designed for high-efficiency, high-density power conversion with fast transient response and integrated protection features.

Key Product Features

• Wide operating range with 12 Vin optimized (8–18 V) and Wide Vin (8–36 V) options
• Wide output range: Vout 1–16 V
• Low-temperature variants: LGIZ (-40°C) and LGMZ (-55°C)
• Internal compensation and minimal external components for faster development
• High peak efficiency: >96% (24 Vin → 12 Vout) and >95% (12 Vin → 5 Vout); efficient across light and full load
• Flexible features: frequency synchronization, user-adjustable soft-start and tracking
• Constant voltage or constant current operation with dedicated error amplifier and reference
• Paralleling and single-wire current sharing; two-phase interleaving
• Protections: Input OVLO/UVLO, Output OVP, Over Temperature Protection (OTP)
• High-density HV ZVS‑Buck topology; family supports wider input up to 36–60 V
• Very-fast transient response
