| 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 cu... |
