DescriptionThe LTC1753CG is one member of the LTC1753 family which is designed as the high power, high efficiency switching regulator controller that can be used in high power 5V to 1.3V-3.5V regulators and power supply for Pentium® II, AMD-K6®-2, SPARC, ALPHA and PA-RISC microprocessors. This device includes a soft start circuit which is used for initial start-up and during current limit operation, a feedback loop to control operation in current limit.
Features of the LTC1753CG are:(1)5-bit digitally programmable 1.3V to 3.5V fixed output voltage; (2)fast transient response: 0% to 100% duty cycle; (3)phase lead compensation for remote sensing; (4)over-temperature protection; (5)flags for power good and overvoltage fault; (6)19A output current capability from a 5V supply; (7)dual N-channel MOSFET synchronous driver; (8)initial output accuracy: ±1.5%; (9)excellent output accuracy: ±2% typ over line, load and temperature variations; (10)high efficiency: over 95% possible; (11)adjustable current limit without external sense resistors; (12)available in 2O-lead SSOP and SW packages.
The absolute maximum ratings of the LTC1753CG can be summarized as:(1)Vcc:7 V;(2)PVcc:14 V;(3)digital output voltage:-0.3V to 9V;(4)IFB input current:-100mA;(5)junction temperature:125°C;(6)operating temperature range:0°C to 70°C;(7)storage temperature range:-65°C to 150°C;(8)lead temperature (soldering, 10 sec.):300°C.
