The LT3799-1 is an isolated flyback controller with power factor correction specifically designed for driving LEDs. The controller operates using critical conduction mode allowing the use of a small transformer. Using a novel current sensing scheme, the controller is able to deliver a well regulated current to the secondary side without using an opto-coupler. A strong gate driver is included to drive an external high voltage MOSFET. Utilizing an onboard multiplier, the LT3799-1 typically achieves power factors of 0.97. The FAULT pin provides notification of open and short LED conditions. The LT3799-1 offers improved line regulation over the LT3799, but is not designed for use with a TRIAC dimmer.The LT3799-1 uses a micropower hysteretic start-up to efficiently operate at offline input voltages, with a third winding to provide power to the part. An internal LDO provides a well regulated supply for the part?s internal circuitry and gate driver.

Demo circuit 1818A features the LTM8001 μModule regulator that includes a 5A switching regulator and an array of five 1.1A low noise LDOs. The demo board operates from a 6V to 36V input and is configured so the switching regulator provides an output that also powers the LDOs. The LDOs in turn provide three outputs – one from a single LDO and two outputs each formed by paralleling two LDOs together.

The LT1786F is a fixed frequency, current mode, switching regulator that provides the control function for Cold Cathode Fluorescent Lighting (CCFL). The IC includes an efficient high current switch, an oscillator, output drive logic, control circuitry and a micropower 6-bit 100?A full-scale current output DAC. The DAC provides simple ?bits-to-lamp-current control? and communicates using the 2-wire SMBus serial interface. The LT1786F acts as an SMBus slave device using one of two selectable SMBus addresses set by the address pin ADR.On Power-up, the DAC output current assumes midrange or zero scale, depending on the logic state of the ADR pin.The entire IC can be shut down through the SMBSUS pin or by setting the SHDN bit = 1 in the SMBus command byte. Digital data for the DAC output current is retained internally and the supply current drops to 40?A for standby operation. The active low SHDN pin disables the CCFL control circuitry, but keeps the DAC alive. Supply current in this operating mode drops to 150?A.The LT1786F control circuitry operates from a logic supply voltage of 3.3V or 5V. The IC also has a battery supply pin that operates from 4.5V to 30V. The LT1786F draws 6mA typical quiescent current. A 200kHz switching frequency minimizes magnetic component size. Current mode switching techniques with cycle-by-cycle limiting gives high reliability and simple loop frequency compensation. The LT1786F is available in a 16-pin narrow SO package.Applications Notebook and Palmtop Computers Portable Instruments Personal Digital Assistants
