| Description | The IS32LT3958 is a current mode PWM controller designed to drive a low side external NMOS FET for wide input/output voltage range and high LED current applications. An external resistor senses the high side output current of the LED string. A high side sense resistor is the most flexible current sensing scheme, since it functions in either boost or buck-boo. |
| Features | two independent analog dimming pins, ICTRL and ADJR. Input DC voltage in the range of 0.06V~2V on the ICTRL pin and/or ADJR pin is required for analog dimming. PWM dimming is achieved by directly modulating the PWM/EN pin with desired PWM duty cycle or by enabling the internal PWM generator circuit. With the internal PWM generator circuit, IS32LT3958 can achieve standalone dual brightness level output. The duty cycle and frequency of the internal PWM generator is easily programmed by external resistors. The IS32LT3958 is available in an eTSSOP-20 package with an exposed pad for enhanced therma. |
