3V to 13.2V Input • 0.5V to 5.5V Output
5.4 Transient Response
The pictures below show the deviation of the output
voltage in response to the 50-100-50% step load at
1A/µs. In all tests the ZY7120 converters were
switching at 1MHz and had 5x22µF and 5x47µF
ceramic capacitors connected across the output
pins. Bandwidth of the feedback loop was
programmed for faster transient response.
