The LTM4651 operates over a 3.6V to 58V input voltage range and is housed in a 15mm x 9mm x 5.01mm BGA package, providing –5V, –12V, –15V and –24V outputs from a standard 5V, 12V or 24V supply. The regulator is designed to meet the EN55022 Class B EMC standard for Information Technology Equipment in harsh environments such as test and measurement, industrial, factory automation, process control, medical devices, imaging and communications.

It includes a DC-DC inverting regulator, inductor, MOSFETs and compensation circuitry and is designed as a standalone inverting regulator without need of any external circuitry such as level shifters.

The output current capability is up to 4A or 24W of output power, and multiple devices can be operated in parallel. The supported switching frequency range is 250kHz to 3MHz, set by a single resistor. It features overcurrent and overtemperature protection with a temperature range of –40°C to 125°C. 1,000-piece pricing starts at $14.75 each.
