描述
由其分销商提供的 onsemi UC3845BD1G 的描述。
UC3845B Series 36 V 275 kHz High Performance Current Mode Controller - SOIC-8
CURRENT MODE PWM CTRL, SOIC-8; Input Voltage: -; Output Voltage: 13.4V; Output Current: 200mA; Supply Voltage Min: 12V; Supply Voltage Max: 25V; Controller IC Case S; Available until stocks are exhausted Alternative available
The UC3844B UC3845B series are high performance fixed frequency current mode controllers. They are specifically designed for Off-Line and dc-to-dc converter applications offering the designer a cost-effective solution with minimal external components. These integrated circuits feature an oscillator a temperature compensated reference high gain error amplifier current sensing comparator and a high current totem pole output ideally suited for driving a power MOSFET. Also included are protective
