Regulated DC/DC converter ZVS

non-isolatedSIPfor telecommunications equipment

Overview
PI3325-00-LGIZ is a ZVS (Zero-Voltage Switching) buck regulator from the PI33xx family, engineered for high-density power conversion. Typical example configuration: 24 V input, 5 V output, 20 A maximum output current. Package: 10x14 LGA-SIP (14.0 x 10.0 x 2.56 mm). Lead time: 28 weeks. Minimum order quantity: 1.

Product features

• Wide operating ranges for Vin and Vout (Vout 1–16 V supported)
• Optimized Vin variants (12 Vin optimized 8–18 V and wide Vin 8–36 V); family supports higher HV ranges
• High peak efficiency (>96% peak 24 Vin → 12 Vout; >95% peak 12 Vin → 5 Vout)
• Internal compensation: minimal external components for fast development
• Frequency synchronization; user-adjustable soft-start and tracking
• Constant-voltage and constant-current operation with dedicated error amplifier and reference
• Paralleling and single-wire current sharing; two-phase interleaving
• Fast transient response and common protections: OVLO/UVLO, OVP, OTP
• Common high-density packaging platform
