February 6, 2013 – Linear Technology Korea (CEO Hong Sa-kwak) has launched the LTM8045, a 2.8V-18V input, multi-topology DC/DC µModule® converter. This product features an onboard inductor, power switch, and DC/DC controller, delivering a maximum output current of 700mA. By adding only two resistors and two capacitors, the LTM8045 can be configured to regulate a positive output voltage between 2.5V and 15V (SEPIC topology) or a negative output voltage between -2.5V and -15V (inverting topology). The LTM8045 is designed for Point-of-load (PoL) regulation in communications, imaging, and handheld test equipment applications.

In SEPIC configuration, the LTM8045 input voltage can be greater than, less than, or equal to the regulated output voltage. When configured as a negative output inverter, the logic-level control pin does not require a level-shift circuit. The LTM8045 achieves 80% efficiency at 12V input and -5V, 500mA load conditions. The operating frequency range is 200kHz to 2MHz, which can be adjusted through an external resistor and synchronized to an external clock within the same frequency range.

The LTM8045 is supplied in a 6.25mm x 11.25mm x 4.92mm BGA package and operation is guaranteed over internal temperature ranges of -40°C to +125°C and -55°C to +125°C. Pricing starts at $6.97 per unit at 1,000-unit quantities. The LTM8045 is available now. For more information, refer to www.linear.com/product/LTM8045参照.
