Product Description
STMicroelectronics L6566BH is a 16-pin SOIC 5-channel PWM controller designed to support both isolated and non-isolated switch mode power supplies (SMPS). It operates at a maximum switching frequency of 300 kHz and functions reliably within a supply voltage range from 10.6V to 23V. This device uses flyback topology ideal for AC-DC and DC-DC power management applications.
Equipped with zero power detection, the L6566BH enhances energy efficiency and system robustness by minimizing power consumption during standby modes. The controller outputs a precise 5.07V voltage across its five outputs, supporting a maximum duty cycle of 75% to optimize power conversion.
This PWM controller exhibits a low startup supply current of 250μA and a typical operating current of 4.6mA, making it suitable for power-sensitive designs. It is engineered to operate in harsh conditions with a temperature rating from -40°C to 150°C, ensuring durability in industrial environments.
The compact SOIC package measures 10mm in length, 4mm in width, and 1.75mm in height, compatible with surface mount mounting technology. It integrates comprehensive protection features for increased reliability in switch mode power supplies used in automotive, industrial, and commercial electronics sectors.
