dc1219a-b DC1219A-B LT3495BEDDB Demo Board | Micropower 3-6VIN to 15VOUT at 75mA Demonstration circuit 1219A-A, A-B, A-C and A-D are micropower low noise boost converters with output disconnect featuring the four different LT3495 versions: LT3495 (0.65A switch current, switching frequency above audible range), LT3495B (0.65A switch current), LT3495-1 (0.35 switch current, switching frequency above audible range) and LT3495B-1 (0.35A switch current). All versions convert a 3V-6V source to 15V. The A-A and A-B versions supply 75mA at 3VIN, while the A-C and A-D supply 36mA.? All versions feature a low noise control scheme, integrated output disconnect function, dimming control and a single output sense resistor. ? ? DC1219A-B
