Микросхема M51996

M51996- RADIATION HARDENED HIGH EFFICIENCY, 5 AMP SWITCHING REGULATOR, SOP-16

 

Особенности, параметры, характеристики

• 500kHz operation to MOS FET
• Output current : ±1 A
• Output rise time 60 ns, fall time 40 ns
• Modified totempole output method with small through current
• Compact and light-weight power supply
• Small start-up current : 100 µA typ.
• Big difference between "start-up voltage" and "stop voltage" makes the smoothing capacitor of the power input section small.
• Start-up threshold 16 V , stop voltage 10 V
• Packages with high power dissipation are used to with-stand the heat generated by the gate-drive current of MOS FET.
• 14-pin DIP, 16-pin SOP 1.5W (at 25°C)
• Simplified peripheral circuit with protection circuit and built-in large-capacity totempole output
• High-speed current limiting circuit using pulse-by-pulse method (CLM+pin)
• Over-voltage protection circuit with an externally re-settable latch (OVP)
• Protection circuit for output miss action at low supply voltage (UVLO)
• High-performance and highly functional power supply
• Triangular wave oscillator for easy dead time setting
• SOFT start function by expanding period 

 

 

Применение

• Feed forward regulator, fly-back regulator
