Introduction

AI Translation

U6117SA is a high-performance primary-side controller that delivers high-accuracy constant voltage (CV) and constant current (CC) output performance, making it especially suitable for low-power offline charger applications. Additionally, U6117SA supports quasi-resonant buck-type LED CC/CV output applications — simply short the SEL pin to the GND pin to enable this mode.

In CV output mode, U6117SA employs a multi-mode operation combining amplitude modulation (AM) and frequency modulation (FM) control, improving system efficiency and reliability. In CC output mode, the device uses FM control and integrates CC compensation for both line voltage and load voltage. U6117SA enables noise-free operation while ensuring excellent dynamic performance. The integrated line-loss compensation function delivers high-performance CV output.

U6117SA integrates multiple protection features: VDD undervoltage lockout (UVLO), VDD OVP, cycle-by-cycle OCP, short-circuit protection (SLP), and VDD clamping.
