The MH6207 is a high voltage buck control IC for constant LED current regulation. The MH6207 operates constant off-time mode. It allow efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 8VDC up to 450VDC or 110VAC/220VAC.
The MH6207 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, and the dimming also accept a 0-1.2V linear input signal. The RNTC pin can accept a 0-250mV Line Dimming input witch be used for temperature compensation of the LED current.
MH6207 is available by SOP-8 packages
