Linear Introduce Inverting Boost Or Buck-Boost µModule Converter

The LTM8045 is designed for point-of-load regulation in communications, imaging and handheld test equipment.

In the SEPIC configuration, the LTM8045’s input voltage can be above, below or equal to the regulated output voltage. If configured as a negative output inverter, no level shifting circuitry is required by the logic level control pins. Under a -5V, 500mA load, the LTM8045 achieves 80% efficiency from a positive 12V input supply. The operating frequency range is 200kHz to 2MHz, adjustable via an external resistor and can be synchronized to an external clock within the same frequency range.

The LTM8045 is packaged in a 6.25mm x 11.25mm x 4.92mm BGA and operation is guaranteed over the -40°C to +125°C and -55°C to +125°C internal temperature range. Pricing starts at $6.97 each for 1,000 piece quantities. The LTM8045 is available for immediate delivery from stock.
