Microchip 16-Pin SOIC 5-Channel Current Mode PWM Controller 3 MHz 13.5V HV9123NG-G

Microchip HV9123NG-G is a 16-pin SOIC package current mode PWM controller designed for high-voltage and high-frequency power management applications. Operating at a maximum switching frequency of 3 MHz and a maximum supply voltage of 13.5V, this device delivers reliable performance for various industrial and commercial power supply designs.

This PWM controller features five output channels capable of driving loads with a maximum output current of 10mA. Its low supply current of 1.3mA complements its high efficiency, making it suitable for power supplies ranging from 1W to over 50W output levels. The device supports a wide input voltage range from 10V up to 450V, enabling versatility for off-line high-frequency power supply usage.

The HV9123NG-G includes an internal ±2% bandgap voltage reference, internal operational amplifier, and a very high-speed comparator which together provide precise current mode control. The device’s surface mount SOIC package with dimensions of 10mm length, 4mm width, and 1.65mm height supports compact PCB designs. It performs effectively in harsh environments thanks to an operating temperature range spanning -55°C to 125°C.

Its features such as remote on/off controls allow latching or nonlatching shutdown modes, reducing power consumption under shutdown conditions to less than 6mW. Its robustness and design enable the creation of rugged, efficient switch mode power supplies with galvanic isolation limited by magnetic assembly insulation only.

Typical applications include universal input power supplies, off-line high-frequency power supplies, high-density power supplies, and other power electronics requiring a broad load range and exceptional efficiency. This product is a member of the HV91 series and meets industrial standards for reliable PWM controller operation.

High switching frequency of up to 3 MHz allows for fast and efficient power conversion. Supports a 10 to 450V input voltage range ensuring flexibility in various power supply designs. Low supply current of 1.3mA enables energy-efficient operation.

Offers five output channels with a 10mA output current and maximum duty cycle of 99%. Robust operation over a temperature range of -55°C to 125°C for industrial applications. Surface mount SOIC package with a compact size of 10mm length, 4mm width, and 1.65mm height.

Internal ±2% bandgap reference and high-speed comparator ensure precise current mode PWM control. Ideal for use in switch mode power supply (SMPS) controllers and universal input power supplies. Remote on/off controls support latching or nonlatching remote shutdown, minimizing power during shutdown.
