DC/DC Controller Converts With Up To 98% Efficiency At 250 W

Feb. 15, 2013
Synchronous buck-boost dc/dc controller operates from input voltages above, below or equal to the regulated output voltage.

The LT8705 from Linear Technology is a high efficiency (up to 98%) synchronous buck-boost dc/dc controller that operates from input voltages above, below or equal to the regulated output voltage. The device has four feedback loops to regulate the input and output current/voltage. The input current/voltage feedback loops can prevent overloading of solar cells. The output current loop provides a regulated output current for a battery charger or current source. The controller can be used in a range of applications such as a voltage stabilizer in telecom and automotive requirements, as well as in solar or high impedance sources and battery systems. Operating over a 2.8 V to 80 V input voltage range, it produces a 1.3 V to 80 V output, using a single inductor with 4-switch synchronous rectification. Operating frequency is selectable between 100 and 400 kHz, and output power up to 250 W can be delivered with a single device. The LT8705 is available in a 38-pin 5 x 7 mm QFN, and also a 38-lead TSSOP package with additional pin spacing for high voltage operation. Pricing starts at $5.95 each/1,000.
