E48SH3R330NRFA Integrated Circuit Chip 1/8 Brick 3.3V 30A DC/DC Converter

The E48SH3R330 is a 1/8-brick (Eighth Brick) isolated single-output DC-DC power module featuring a standard pin-out package and through-hole mounting. It accepts an input of 36–75 V (nominal 48 V) and delivers an output of 3.3 V / 30 A, with a rated power of 120 W, 2,250 V isolation, and a secondary-side control architecture. It is specifically designed for step-down power supply to 48 V communication buses, offering excellent electrical and thermal performance as well as high reliability.

• Full-load efficiency up to 92% (3.3 V / 30 A), fixed-frequency operation, and fast transient response.
• Comprehensive protection: input under-voltage lock-out (UVLO), output over-voltage (OVP), over-current (OCP), and over-temperature (OTP) protection.
• Supports monotonic start-up with pre-biased loads; no minimum load required; no negative current during switching or enable/disable operations.
• Industrial-standard 1/8-brick pinout and form factor, dimensions 58.4 × 22.8 × 9.5 mm; 2,250 V isolation and basic insulation.
• Supports remote switch control and a wide operating temperature range.
• Compliant with UL/IEC/EN 62368-1 and 60950-1 safety certifications; production lines hold quality system certifications such as ISO/TL9000.

• Wireless communication equipment, telecommunications base stations, servers, and network switches.
• Industrial equipment, data communication infrastructure, and 48 V bus power supply systems.
• ITE (Information Technology Equipment), such as FPGAs and processors, and other on-board 3.3 V high-power supply applications.
