Shindengen Launched MCZ5216ST LLC Current Resonant Mode Controller IC, Reducing 25% Power Consumption During Standby

时间： 2023-07-28 来源：Shindengen News

技术问答

LLC current resonance circuits are used to achieve higher efficiency and lower noise in 100-500W output class power supplies. The newly developed MCZ5216ST is an LLC Current Resonant Mode Controller IC that combines the functionality of the previous MCZ5211ST with built-in X condenser discharge functionality. Incorporation of this X condenser discharge functionality allows for an approximately 25% reduction in power consumption during standby.

Moreover, SHINDENGEN's original control method (asymmetric control) provides the chip with an active-standby function which improves power efficiency during light loads (of several W) and standby, which makes it possible to eliminate the need for the auxiliary power supplies required up until now. The chip also allows for the operating frequency to be increased up to 500kHz, contributes to power supply miniaturization, and is equipped with a variety of protection functions, making it possible to construct a power supply circuit with a small number of component parts.

※During no load condition, compared to Shindengen conventional model.

Features

Built-in X condenser discharge functionality
Input voltage detection mode can be selected from either AC or DC
Allows for transmission of IC operating status through a photo-coupler using a power-good signal (in AC input detection mode)
LLC individual IC equipped with HV Startup (600V withstand voltage starter circuit)
Compatible with higher frequencies - Capable of constant operation frequencies of 500kHz
Low standby power (built-in active standby function and burst function)
Built-in oscillation frequency compensation function using input voltage during burst (in DC input detection mode)

Typical Applications

Power supplies for LBP and other document equipment
Power supplies for audio equipment
Power supplies for FPD
Power supplies for LED lighting
Power supplies for industrial equipment
