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

Microchip HV9123NG-G is a high-voltage current-mode 5-channel PWM controller packaged in a 16-pin SOIC form factor. Operating at a maximum switching frequency of 3 MHz and supporting supply voltages up to 13.5V, this versatile controller enables efficient switch mode power supply (SMPS) designs.

The HV9123NG-G devices are designed to self-start directly from a wide range of DC inputs including 12V batteries and rectified 240VAC lines. They improve efficiency by drawing operating power from converter outputs while providing galvanic isolation limited only by the magnetic assembly insulation.

Key features include a ±2% internal bandgap reference, internal operational amplifier, high-speed comparator, and output buffer, facilitating the production of rugged and highly efficient power supplies delivering 50W or more, with efficiency exceeding 80% even at low output powers of 1W or less.

This device supports remote on/off control with latching and non-latching shutdown mechanisms, maintaining a low shutdown power requirement of less than 6 mW. Its compact dimensions of 10 mm length, 4 mm width, and 1.65 mm height allow use in space-constrained designs.

The operating temperature range of -55°C to 125°C and surface mount SOIC package make it suitable for various industrial and high-density power supply applications. The maximum duty cycle of 99% and five output channels with 10 mA current output enable versatile PWM control tasks.

Typical applications include offline high frequency power supplies, universal input power supplies, very high efficiency power supplies, high-density power supplies, and extra wide load range power supplies.
