LINEAR TECHNOLOGY
The LTC3810EG#PBF is a 100V current mode synchronous switching Regulator Controller can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The LTC3810 uses constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifier provides very fast line and load transient response. Large 1Ω gate drivers allow the LTC3810 to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. A shutdown pin allows the LTC3810 to be turned off, reducing the supply current to 240μA. High voltage operation up to 100V Large 1Ω gate drivers No current sense resistor required Dual N-channel MOSFET synchronous drive Extremely fast transient response ±0.5% 0.8V Voltage reference Programmable output voltage tracking/soft-start Generates 10V driver supply from input supply Synchronizable to external clock Selectable pulse skip mode operation Power good output voltage monitor Adjustable on-time/frequency (tON (min) Adjustable cycle-by-cycle current limit Programmable under-voltage lockout Output overvoltage protection Supply Voltage Min: 6.2V Supply Voltage Max: 100V No. of Outputs: No. of Outputs: 1 Output Duty Cycle (%): - Controller IC Case Style: SSOP No. of Pins: 28Pins Switching Frequency: 1MHz Topology: Synchronous Buck (Step Down) Operating Temperature Min: -40°C Operating Temperature Max: 125°C Packaging: Cut Tape Product Range: - Automotive Qualifications Standard: - MSL: MSL 1 - Unlimited Output Current: 10 A SVHC: No SVHC (17-Dec-2015) Find similar products grouped by common attribute
