Regulated DC/DC converter ZVS

non-isolatedSIPindustrial

Overview
PI3523-00-LGIZ is a member of the PI352x family of ZVS (Zero-Voltage Switching) Buck Regulators. It provides high-efficiency DC-DC conversion from high-voltage rails to low-voltage outputs for high-density power applications. Typical application parameters: input 48 V (family supports 36–60 V and 30–60 V options); example output 3.3 V (family supports 2.2–14 V); maximum output current 22 A; package 10 x 14 LGA SiP. Mechanical outline and footprint references are provided by the manufacturer.

Key Features

• 48 Vin options (36–60 V and 30–60 V across family)
• Wide Vout support (2.2–14 V across family; example 3.3 V)
• Operating temperature variants: LGIZ -40°C, LGMZ -55°C
• Simple integration with internal compensation and few external components
• High peak efficiency (>96% at 48 Vin) and strong light-load performance
• Feature set: frequency synchronization, user-adjustable soft-start & tracking
• Paralleling and single-wire current sharing; two-phase interleaving
• Protections: OVLO/UVLO, OVP, OTP
• Common high-density packaging platform: 10 x 10 x 2.6 mm and 10 x 14 x 2.6 mm LGA SiP
• Very-fast transient response and constant-voltage or constant-current operation
