LTC3200 Lithium-Ion Battery to 5V White or Blue LED Driver

A new charge-pump architecture maintains constant switching frequency to zero load and reduces bith output and input ripple. The LTC3200/LTC3200-5 have thermal shutdown capability and can survive a continuous short-circuit from V_OUT to GND. Built-in soft-start circuitry prevents excessive inrush curreent during start-up.
