Half Bridge Driver, Separate High and Low Side Inputs, Inverting Low Side Input, Fixed 520ns Deadtime in a 8-pin DIP package; A IR2103 packaged in a Lead-Free 8-Lead PDIP
The maximum operating frequency of the IR2103PBF is 500 kHz, but it can be operated up to 1 MHz with some limitations on the deadtime and minimum pulse width.
The deadtime of the IR2103PBF can be calculated using the formula: Deadtime (ns) = 1000 / (Fsw x 2), where Fsw is the switching frequency in kHz.
The minimum input pulse width required by the IR2103PBF is 100 ns, but it's recommended to use a minimum pulse width of 200 ns to ensure reliable operation.
Yes, the IR2103PBF can be used with a bootstrap capacitor to generate the high-side gate drive voltage. However, the bootstrap capacitor value and charging resistor should be carefully selected to ensure reliable operation.
To protect the IR2103PBF from shoot-through current, it's recommended to use a deadtime of at least 100 ns and ensure that the high-side and low-side FETs are not turned on simultaneously.
