DC-DC Converters

Product Information

MQ7854

40~60Vdc Input, Quad Output 20W power module, specific for WiMAX CPE Device

Description

The MQ7854 Power Modules are non-isolated dc-dc converters that operate over a wide input voltage range of 40Vdc to 60Vdc and provide a precisely (3%) regulated dc output with quad output -- 6.5V for RF power circuit, 4V for RF front-end circuit, 3.3V and core voltage for digital circuit. The modules with small size, have a maximum 20W output power. Standard features include power sequency for 3.3V and core voltage, core voltage trim function, over-current protection.

Features

• Wide input range: 40~60V
  
• wide trim range: 1.2~1.8V(for core voltage)
  
• ±3% set-point accuracy
  
• Low Noise
