• Manufacturer Part Number: TS2576CM5-12
• Description: 3A Step Down Switching Voltage Regulator
• Manufacturer: TSC [Taiwan Semiconductor Company, Ltd]

Note 1: External components such as the catch diode, inductor, input and output capacitors can affect switching regulator
Note 2: The oscillator frequency reduces to approximately 11KHz in the event of fault conditions, such as output short or
Note 3: For these parameters, FB is removed from V
Note 4: V
Note 5: FB is removed from V

self-protection feature lowers the average power dissipation by lowering the minimum duty cycle from 5% down to
approximately 2%.
