L6562AD

The L6562AD is a current-mode PFC Controller operating in transition mode (TM). Coming with the same pin-out as its predecessors L6561 and L6562 it offers improved performance. The highly linear multiplier includes a special circuit able to reduce AC input current distortion that allows wide-range-mains operation with an extremely low THD even over a large load range. An effective 2-step OVP enables to safely handle overvoltage either occurring at start-up or resulting from load disconnection. The totem-pole output stage, capable of 600mA source and 800mA sink current and is suitable to drive high current MOSFETs or IGBTs. This combined with the other features and the possibility to operate with the proprietary fixed-off-time control, makes the device an excellent solution for EN61000-3-2 compliant SMPS in excess of 350W.

• Proprietary multiplier design for minimum THD
• Very accurate adjustable output over-voltage protection
• Ultralow (30µA) start-up current
• Low (2.5mA) quiescent current
• Digital leading-edge blanking on current sense
• Disable function on E/A input
