IR2153S application circuit, circuit diagram & datasheet

IR2153 Pinout Equivalent

The IR2153 is a self-oscillating half-bridge driver from Infineon Technologies for power semiconductors, microcontrollers, sensors and security ICs. It is widely used in high-frequency switching scenarios such as fluorescent lamp ballasts, DC-AC inverters and other applications due to its high side-drive advantages.When the designer needs to find a device that can replace IR2153 due to the lack of devices, he needs to consider other factors such as the performance and cost of the alternative device. Next, I will introduce the pin functions of IR2153 and recommend the alternative devices.
Here is the detailed pin definition and functional description of the IR2153

Alternative model recommendation

When using a replacement device for the IR2153, you need to pay attention to the performance of the device, its availability, and whether the device’s pinout function is the same as that of the IR2153, to determine whether it can be replaced directly or whether you need to re-plan the layout of the PCB.

The flagships of the following models have the same pin arrangement as the IR2153 and can be directly replaced, but the differences in device frequency/current parameters need to be noted:

Picture	Manufacturer	Model Number	Key Differences / Strengths	Features
	Infineon	IR21531	Dead zone time is shorter (0.5 μs)	High-frequency switching power supply
	STMicroelectronics	L6569	Integrated bootstrap diode simplifies peripheral circuitry	Compact power design
