1.2A(IOUT), 1.5MHz High Input Voltage Switching Regulator with MILPITAS, CA - July 30, 2009 - Linear Technology Corporation announces the LT3663, a 1.2A, 1.5MHz monolithic current mode step-down switching regulator with a programmable output current limit. Its wide operating input voltage of 7.5V to 36V makes the LT3663 ideal for a variety of input sources, including unregulated 12V wall adapters, 24V industrial supplies, Fire Wire, as well as automotive applications. Onboard input overvoltage lockout protects the device through input transients as high as 60V, such as those commonly found in automotive applications. Both the LT3663’s output voltage and output current are adjustable. Output voltages as low as 0.8V are set by a resistor divider whereas its output current is user programmable between 0.4A to 1.2A via an external resistor. The LT3663 utilizes a 1.5MHz oscillator, internal compensation and an internal boost diode to minimize the overall solution footprint. Combined with a 2mm x 3mm DFN package it offers a very compact high voltage regulator. Pricing for the LT3663EDCB starts at $2.50 for 1,000-piece quantities. The LT3663IDCB is tested and guaranteed to operate from a -40ºC to 125ºC operating junction temperature and is priced at $2.94 in 1,000-piece quantities. All versions are available from stock.
