Linear Technology, a manufacturer of high-performance integrated circuits, has released the LTC3245, a 25mA high voltage buck-boost charge pump. According to the company, the LTC3245 is ideally suited for “low power, space-constrained automotive and industrial applications, such as automotive ECU/CAN transceiver supplies, industrial housekeeping supplies and efficient low power 12V to 5V conversion” because of the device’s low operating current and low external device count.
The LTC3245 employs “switched capacitor fractional conversion to maintain regulation over a wide range of input voltage from 2.7V to 38V, and produces a regulated output of 3.3V, 5V or adjustable (2.5V to 5V).” The device features pin-selectable burst mode operation, “which allows the user to trade off low-output ripple for better efficiency/lower quiescent current,” according to Linear Technology. Additional IC features include low external parts count with ceramic capacitor stability, soft-start circuitry to prevent excessive current flow during startup, as well as short circuit and thermal protection.
The LTC3245 is available from Linear Technology in a low-profile (0.75mm) 3mm x 4mm 12-lead DFN with backside thermal pad and a 12-lead MSOP package with backside thermal pad. E- and I-grade operating junction temperature is -40°C to 125°C, while H-grade operating junction temperature is -40°C to 150°C.
