A Product Line of Diodes Incorporated PAM99700 UNIVERSAL HIGH BRIGHTNESS LED DRIVER Description The PAM99700 is an open loop current mode control LED driver IC. The PAM99700 can be programmed to operate in either a constant frequency or constant off-time mode. It includes a 12 - 500V regulator which allows it to work from a wide range of input voltages without the need for an external low voltage supply. The PAM99700 includes a PWM dimming input that can accept an external control signal with a duty ratio of 0 - 100% and a frequency of up to a few kilohertz. It also includes a 0 - 250mV linear dimming input which can be used for linear dimming of the LED current. The PAM99700 is ideally suited for buck LED drivers.
