AP3019AKTR-G1

AP3019AKTR-G1 is a Diodes Incorporated white-LED driver in SOT-23-6, tape and reel — a boost constant-current stage for small backlight strings, with device marking GAS. The maker's ordering table carries only this code: K is the SOT-23-6 package, TR tape and reel, G1 the lead-free/green finish, rated −40 to +85 °C. The selection point is the low 200 mV feedback: the reference is 188 mV minimum, 200 mV typical and 212 mV maximum at 20 mA through 4 LEDs over the full temperature range, so the current-sense resistor burns far less power than a 1.25 V-reference boost — the difference matters in battery-fed backlights. Switching runs at 0.9 MHz minimum, 1.2 MHz typical and 1.5 MHz maximum; the feedback figures are stated at VIN = VCTRL = 3 V and the frequency at TA = 25 °C. Selection advice: order this code under the maker's SOT-23-6 naming — the similar TSOT-23-6L label belongs to a different ordering code (AP3019AKTTR-G1) and is not this part. No current lifecycle status was verified for this code in this review, so none is claimed here — supply is confirmed per order against the exact code. Parameters verified against the Diodes DS41298 Rev. 4-2 datasheet.
