Small packaged output voltage regulator for surface mount applications for heavy equipment control and avionics
60v surface mount output voltage regulator
Linear Technology introduces the LTM8027, a 4A system-in-a-package DC/DC ”Module regulator capable of operating from a 60V supply without any input protection. The LTM8027 includes the inductor, power switches, switching regulator and all support components in a small 2.6g 15mm x 15mm x 4.32mm land grid array (LGA) plastic package. The device can regulate an output voltage ranging from 2.5V to 24V from an input supply of 4.5V to 60V (65V absolute maximum). The LTM8027's rugged voltage rating makes it a suitable voltage regulator for 12V and 24V automotive and heavy equipment such as industrial robotics, 48V telecom, as well as Avionics and industrial control systems.

The LTM8027's operating frequency can be adjusted with a resistor from 100kHz to 500kHz or the device can be synchronized to an external clock to optimize efficiency for a given input-to-output voltage ratio or to prevent the device from interfering with a system's sensitive operating frequency. Because of synchronous switching of the internal MOSFETs, the LTM8027 can deliver 4A at 12VOUT from 24VIN with 93% efficiency. The device draws only 10”A when in shutdown.

The LTM8027 is offered in temperature grades of -40șC to 125șC and -55șC to 125șC. 1,000-piece price starts at $16.50 each.
