DP2539 is a high-performance off-line PWM power switch for low-power AC / DC chargers and adapter applications.
DP2525 is a low cost and high performance Primary Side Regulation (PSR) controller for offline small power converter applications which can provide very tight output voltage regulation (CV) and output current control (CC) ideal for charging applications.
DP9128V is a highly integrated step-down quasi-resonant LED constant current driver switch.
DP9129 is a highly integrated power switch with Quasi-Resonant Buck (QR-Buck) constant current (CC) control for LED lighting applications.
DP9126IX series is a highly integrated constant current LED power switch, the chip uses a quasi-resonant mode of operation, while active power factor correction control technology to meet the high power factor, low harmonic distortion and high efficiency performance.
