Linear Technology Corporation announces a new high reliability MP-grade, wider temperature range version of the LTC3245, a versatile 250mA high voltage buck-boost charge pump.

LTC3245MPThe MP grade has an operating junction temperature range of -55°C to +150°C. The LTC3245 uses 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). Internal circuitry automatically selects a conversion ratio of 2:1, 1:1 or 1:2 to optimize efficiency as input voltage and load conditions vary. Low operating current (18μA with no load, 4μA in shutdown) and low external device count (three small ceramic capacitors and no inductors) make the LTC3245 ideally suited for low power, space constrained automotive/ applications such as ECU/CAN transceiver supplies, industrial housekeeping supplies and efficient low power 12V to 5V conversion.
