توضیحات محصول

The HT7L5600 is a single-stage, isolated, primary-side offline LED lighting controller that achieves a high power factor. Power control is implemented by controlling an external MOSFET and accurate LED constant current regulation from the primary-side information. This can significantly simplify the LED lighting system design by eliminating the secondary-side feedback components and the normally required opto-coupler. The extremely low start-up current and quiescent current reduces the total power consumption to provide a high efficiency solution for lighting applications. The HT7L5600 provides several protection functions, which include VCC Under Voltage Lockout (UVLO), Over Current Protection (OCP), Output LED String Open Protection, Output LED String Short Protection, VCC Over Voltage Protection (OVP) and Leading-Edge Blanking (LEB) for current  sensing. Additionally and to ensure system reliability, the device includes a fully integrated thermal protection function. To protect the external power MOSFET from being damaged by an over voltage, the device DRV pin voltage is clamped to about 16V.

The high level of functional integration minimises the external component count giving major advantages in terms of cost and circuit board area. The device is supplied in a SOT23-6 package.
