PT4101 : The PT4101 is a step-up DC/DC converter designed for driving up to 5 white LEDs in series from a single cell Lithium Ion battery with constant current. Because it directly regulates output current, the PT4101 is ideal for driving light emitting diodes (LEDs) whose light intensity is proportional to the current passing through them, not the voltage across their terminals. A single external resistor sets LED current between 2mA and 20mA, which can then be easily adjusted using either a DC voltage or a pulse width modulated (PWM) signal up to 100KHz. Its low 104mV feedback voltage reduces power loss and improves efficiency. The OV pin monitors the output voltage and turns off the converter if a.

PT4105 : FEATURES The PT4105 is a step-down DC/DC converter designed to operate as a high current LED driver. The PT4105 uses a voltage mode, fixed frequency architecture that guarantees stable operation over wide range of supply voltages and load conditions. The PT4105 senses the output current by measuring the voltage across an external resistor in series with the high current LED. This voltage is then fed back to the PT4105 to control the PWM signal that drives the switching device to achieve accurate current regulation. The low 200mV feedback voltage greatly reduces the power dissipation on the external current sensing resistor and therefore improves the overall efficiency. The value of the ext.

It allows efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 18VDC up to 450VDC or 110VAC/220VAC. The PT4107 controls an external MOSFET at fixed switching frequency from 25 kHZ to 200 kHZ. The frequency can be programmed using an external resistor. A proprietary peak current control method keeps constant average LED currents for wide input and output ranges. The output current can be programmed from a few milliamps up to more than 1A. The output current on one LED string also can be programmed to any value between zero and its maximum value by applying an external control voltag.
