It can drive 10 or more WLEDs in series from a 2.7V to 5.5V input supply, generating up to 40V output. The device integrates a 1.5A power switch and operates at a fixed 1 MHz switching frequency, enabling the use of small external components. Multiple dimming methods are supported including analog and PWM. Comprehensive protection includes over-current, over-voltage, UVLO, and over-temperature shutdown.","working_principle":"The PAM2841GR uses a current-mode boost converter architecture to step up the input voltage to drive series-connected white LEDs. The internal 1.5A power MOSFET switches at 1 MHz, storing energy in the external inductor during the on-time and transferring it to the LED string during the off-time. LED current is regulated by sensing the voltage across an external current-sense resistor. PWM dimming modulates the LED current on\/off at a high frequency to control perceived brightness. The soft-start function limits inrush current during startup.","pin_description":"
