DC362A-A: Demo Board for the LTC1405 12-Bit, 5Msps, Sampling ADC.

Demonstration Circuit 395A is a Low Noise, Charge Pump White LED Driver featuring the LTC3202. The LTC3202 is a fractional charge pump LED driver that operates from 2.7V to 4.5V (3.3V nominal) and provides up to 125mA of LED current. The demo board includes 6 white LEDs in parallel, supplying approximately 20mA of current per LED.  Controls pins D0 and D1 set the values for the internal 2-bit DAC, which allows LED current to be adjusted for LED brightness control.

The LTC3727A-1 is a high performance dual step-down switching regulator controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows phase-lockable frequency of up to 550kHz. Power loss and noise due to the ESR of the input capacitors are minimized by operating the two controller output stages out of phase.The LTC3727A-1 is an improved version of the LTC3727 family of parts. It has smaller output ripple while in the drop-out condition and shorter minimum on-time.OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. There is a precision 0.8V reference and a power good output indicator. A wide 4V to 30V (36V maximum) input supply range encompasses all battery chemistries.A RUN/SS pin for each controller provides soft-start. Current foldback limits MOSFET heat dissipation during short-circuit conditions. Output overvoltage protection circuitry protects the controller until VOUT returns to normal.

The LTC3413 is a high efficiency monolithic synchronous step-down DC/DC converter utilizing a constant frequency, current mode architecture. It operates from an input voltage range of 2.25V to 5.5V and provides a regulated output voltage equal to (0.5)VREF while sourcing or sinking up to 3A of output current. An internal voltage divider reduces component count and eliminates the need for external resistors by dividing the reference voltage in half. The internal synchronous power switch with 85m? on-resistance increases efficiency and eliminates the need for an external Schottky diode. Switching frequencies up to 2MHz are set by an external resistor.Forced-continuous operation in the LTC3413 reduces noise and RF interference. Fault protection is provided by an overcurrent comparator that limits output current during both sourcing and sinking operations. Adjustable compensation allows the transient response to be optimized over a wide range of loads and output capacitors.Applications Bus Termination: DDR and QDR? Memory, SSTL, HSTL, ...

The LTC4006 is a complete constant-current/constant voltage charger controller for 2-, 3- or 4-cell lithium batteries in a small package using few external components. The PWM controller is a synchronous, quasi-constant frequency, constant off-time architecture that will not generate audible noise even when using ceramic capacitors.The LTC4006 is available in 8.4V, 12.6V and 16.8V versions with ?0.8% voltage accuracy. Charging current is programmable with a single sense resistor to ?4% typical accuracy. Charging current can be monitored as a representative voltage at the IMON pin. A timer, programmed by an external resistor, sets the total charge time or is reset to 25% of total charge time after C/10 charging current is reached. Charging automatically resumes when the cell voltage falls below 3.9V/cell.Fully discharged cells are automatically trickle charged at 10% of the programmed current until the cell voltage exceeds 2.5V/cell. Charging terminates if the low-battery condition persists for more than 25% of the total charge time.The LTC4006 includes a thermistor sensor input that suspends charging if an unsafe temperature condition is detected and automatically resumes charging when the battery temperature returns to within safe limits.Applications Notebook Computers Portable Instruments Battery-Backup Systems Standalone Li-Ion Chargers
