説明
onsemi UC3844BD1Gの詳細は販売業者から提供されます。
UC3844B Series 36 V 275 kHz High Performance Current Mode Controller - SOIC-8
IC, CURRENT MODE CNTRL, 25V, SOIC-8; Input Voltage: -; Output Voltage: 13.5V; Output Current: 1A; Supply Voltage Min: 12V; Supply Voltage Max: 25V; Controller IC Cas; Available until stocks are exhausted Alternative available
Topology = Flyback / Topology = Step-Up / Topology = Step-Down / Outputs = 1 / Output Voltage V = 5 / Output Current A = 1 / Switching Frequency kHz = 52 / Supply Voltage Max. V = 25 / Operating Temperature Min. °C = 0 / Operating Temperature Max. °C = 70 / Package Type = SOIC / Pins = 8 / Mounting Type = SMD / MSL = Level-1 / Packaging = Tube / Length mm = 5 / Width mm = 4 / Height mm = 1.75 / Reflow Temperature Max. °C = 260
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
