 Product Description

900V Offline Switching Regulator

The HF900 is a flyback regulator with an integrated 900V MOSFET. Requiring a minimum number of external components, the HF900 provides excellent power regulation in AC/DC applications that require high reliability. These applications include smart meters, large appliances, industrial controls, and products powered by unstable AC grids.

The regulator uses peak-current-mode control to provide excellent transient response and easy loop compensation. When the output power falls below a given level, the regulator enters burst mode to lower the standby power consumption.

The MPS proprietary 900V monolithic process enables over-temperature protection (OTP) on the same silicon of the 900V power FET, offering precise thermal protection. Also, it offers a full suite of protection features such as VCC undervoltage lockout, over-load protection, overvoltage protection, and short-circuit protection.

The HF900 is designed to minimize electromagnetic interference for wireless communication in home and building automation applications. The operating frequency is programmed externally with a single resistor, so the power supply’s radiated energy can be designed to avoid the interference with wireless communication.

In addition to the programmable frequency, the HF900 employs a frequency jittering function that not only greatly reduces the noise level but also reduces the cost of the EMI filter.
