The LT1310EMSE boost DC/DC converter combines a 1.5A current mode PWM switcher with an integrated phase-locked loop, allowing the user to set the switching frequency anywhere from 10kHz to 4.5MHz. Intended for use in applications where switching frequency must be accurately controlled, the LT1310EMSE can generate 12V at up to 400mA from a 5V input.
Switching frequency is set with an external capacitor, and the device can be operated in either free-running or phase-locked mode. A wide capture range of nearly 2:1 allows the free-running frequency to be set using standard ±10% tolerance NP0 dielectric capacitors.
The LT1310EMSE is available in the tiny thermally enhanced 10-lead MSOP package.
