58VIN, 24W, Negative Output μModule Regulator Meets EN55022 Class B Requirements

Linear Technology Corporation, a member of Analog Devices, Inc., announces the LTM4651, a non-isolated negative-output μModule® (micromodule) regulator that operates from a positive input supply voltage. Generates -26.5V to -0.5V output. The LTM4651 operates from an input voltage range of 3.6V to 58V and is available in a 15mm x 9mm x 5.01mm BGA package. It is a compact solution that provides -5VOUT, -12VOUT, -15VOUT, and - from an industry-standard 5VIN, 12VIN, or 24VIN power supply. 24VOUT. The LTM4651 is designed to meet the EN55022 Class B EMC standard requirements for information technology equipment. The combination of a wide voltage range and low EMI operation makes this device ideal for applications that operate in harsh environments such as test and measurement, industrial, factory automation, process control, medical equipment, imaging, and communications.

The LTM4651 includes a DC/DC negative output regulator, inductor, MOSFET, and compensation circuitry.

The LTM4651's output current capability is up to 4A or 24W output power. For greater output power, multiple LTM4651 devices can be operated in parallel.

The LTM4651's operating temperature range is -40°C to 125°C.
