Previously IR2153 a lot to do with SMPS power supply I shared projects, especially AT, ATX power supply ir2153 pretty it works to evaluate the impact of the power transformer even Yamaha, such as large companies, even 8-pin used in the MOSFET driver integrated product IR2161 if you could call a top version for a long time be aware of before I an integrated but not very common use in DIY environment I did not have the chance to make a trial that we did not already have in our market …
According to the IR2153 integration, the greatest feature of the IR2161 is the built-in current sense short circuit protection system, the power MOSFET is protected against the current drawn through the low-ohmic shunt resistor connected to the source pace, unfortunately the working frequency can not be adjusted with external components, this has a working frequency of 70kHz. I think 34kHz … 70kHz)
GENERAL FEATURES OF IR2161
• Smart half bridge driver
• Short Circuit Protection
• Overload Protection
• External Triggerable Closure
• Over Temperature Protection
• Frequency Modulation (for lower EMI)
• Low Power Start
• phase cut dimmable
• Output Voltage Change Compensation.
• True Bottom Start
• Adaptive Dead Time
