I need to linearly modulate High-Power LEDs with analog signals (sine, triangle wave) within a 1Hz-500Khz frequency range. The driver must also current-limit the LEDs. What Onsemi circuit topology do you have that will accomplish this???

You have not specified your Input voltage and output load.\nYou can refer to our buck topology for instance CAT4201:http://www.onsemi.com/pub_link/Collateral/CAT4201-D.PDF (350mA LED current ) or various dimming methods for NCP3065.\nNCP3065 : http://www.onsemi.com/pub_link/Collateral/AND8298-D.PDF \nOur LED drivers portfolio is available via: http://www.onsemi.com/PowerSolutions/pa ... .do?id=197 \nThank you .
