Overview
MD1800/01 Datasheet High performance primary side regulator (PSR) offline switch power supply (SMPS) controller PRODUCT DESCRIPTION MD180X is high performance primary sensing regulator (PSR) and monolithic switch power controller which is designed for small-power supply equipment with current mode control.
Built-in accurate CV/CC control circuit, eliminates optocoupler, TL431 and its related loop devices.
High integration design, a high performance power BJT and PFM controller and all kinds of protection circuits in one chip, to minimize the peripheral components to save the cost greatly.
MD180X can be simply designed a typical flyback switch converter, the unique driving technology promotes the characteristics of withstand voltage and achieves excellent converting efficiency.
FEATURES ◆ Built-in 700V@MD1800; 810V@MD1801 power BJT.
◆ PSR control, eliminates optocoupler and TL431 ◆ Accurate CV/CC control ◆ Hysteresis over-temperature protection (OTP) circuit ◆ Higher efficiency and meet Level 6 efficiency standards ◆ Output voltage protection (OVP/UVP) ◆ < 100 mW no-load consumption ◆ Auto-Restart function ◆ Ultra-low start-up current ◆ Good EMC characteristic allows the simple EMC circuit APPLICATIONS ◆ Intelligent mobile phone/small size tablet computer ◆ Digital cameras and other small digital products ◆ Power adapters for network products etc.
◆ RCC solutions Replace.
