Microchip 16-Pin SOIC 5-Channel Current Mode PWM Controller 3 MHz 13.5V HV9120NG-G

Microchip HV9120NG-G is a 16-pin SOIC surface mount PWM controller featuring 5 output channels with current mode control and a maximum switching frequency of 3 MHz. It operates with a supply voltage between 9V to 13.5V and consumes only 1.3 mA supply current, making it highly efficient for power management tasks.

This controller is engineered for rugged, high-performance switch mode power supplies (SMPS) that require high efficiency and precise control across a wide dynamic range. Its robust output stage and ±2% internal bandgap reference ensure stable and reliable PWM signals supporting power outputs of 50W or more, while maintaining efficiencies over 80% at low wattage outputs.

The device is suitable for industrial, manufacturing, and commercial applications including off-line high frequency power supplies, universal input power supplies, and very wide load range power supplies. Thanks to its high operating temperature range (-55°C to 125°C), it can maintain stable operation in demanding environmental conditions.

The HV9120NG-G's surface mount SOIC 16-pin package occupies minimal PCB space, facilitating compact design strategies. Remote on/off controls provide flexibility with latching or non-latching shutdown options, with minimal power consumption during shutdown (under 6.0 mW).

This PWM controller is part of the HV91 series by Microchip, optimized for high voltage power supply control, supporting input voltages from 10 to 450V and offering excellent noise immunity and dynamic range. It includes features such as an internal operational amplifier and a high-speed comparator to produce efficient power conversion.

This PWM controller supports a maximum switching frequency of 3 MHz providing precise pulse width modulation control. It features a supply current of 1.3 mA contributing to energy-efficient operation. The device has 5 output channels delivering 10 mA output current suitable for robust power applications.

Operating temperature range spans from -55°C up to 125°C ensuring performance in harsh industrial environments. The controller uses a surface mount SOIC 16-pin package that is compact and easy to integrate into PCBs. The maximum duty cycle is 49.6% allowing fine control of power output and efficiency.

The device is part of the HV91 series designed specifically for high voltage SMPS applications. It includes an internal bandgap reference with ±2% accuracy for stable operation. Designed to self-start from high voltage DC inputs, suitable for off-line high-frequency power supplies.
