ICE3B2065HKLA1 is a monolithic integrated high-voltage power factor correction IC that is specifically designed for low-power AC-DC converters and off-line switchers. It integrates high-voltage switches, PFC controllers and constant-voltage control circuits. It is suitable for applications with a minimum supply voltage of up to 350V AC.

The application field of ICE3B2065HKLA1 spans from CLASS I, CLASS II, street lighting, LED drivers, home appliances, motor drives, telecoms and more. The wide input voltage range allows for a global design for numerous applications, no matter the geography. Moreover, the built-in protections including over temperature, over voltage, under voltage lockout and over power ensure a reliable performance and proper protection of both the converter and the application itself.

Working with the ICE3B2065HKLA1’s principle requires only few components, thus it helps a cost-effective design. This device utilizes an enhanced Zero Voltage Switching Resonant converter topology, improving switching performance compared to traditional zero-current switching type, an enhanced soft-switching converter, which offers high efficiency gains, low EMI and low audible noise. Additionally, the built-in transconductance error amplifier provides regulated output voltage and ripple current control in addition to just power factor correction.

The ICE3B2065HKLA1’s controller is based on critical conduction mode operation allowing the use of an optimized passive part count, with a single electrolytic capacitor in the output stage. This supports less area, higher power density and more flexible total cost of the end system. Its single stage topology has minimum stored energy and soft switching, allowing low THD in the input current and highest power factor. Additionally, the built-in protections against over-voltage, over-current and over-temperature help ensure a steady and resilient performance in any kind of environmental conditions.

Overall, the ICE3B2065HKLA1 is an ideal solution for low-power AC-DC converters and replica hermes braceletoff-line switchers due to its excellent integration and flexibility. It combines several features in a single package to provide not only cost savings but also a more reliable and safe operation of the device. Its wide input voltage range allows a universal design, while the high-voltage switches, PFC controllers and constant-voltage control circuits ensure a steady and robust performance.
