Linear Technology has announced the LT3663, a 1.2 A, 1.5 MHz monolithic current mode step-down switching regulator with a programmable output current limit.
Its wide operating input voltage of 7.5 to 36 makes it suitable for a variety of input sources, including unregulated 12 V wall adapters, 24 V industrial supplies, Fire Wire, as well as motor vehicle applications.
Onboard input overvoltage lockout protects the device through input transients up to 60 V.
Both the device’s output voltage and output current are adjustable. Output voltages to 0.8 are set by a resistor divider whereas its output current is user programmable between 0.4 and 1.2 A via an external resistor. The regulator uses a 1.5 MHz oscillator, internal compensation and an internal boost diode to minimise the overall footprint.
