A paper introduce some ways which is used to Optimizing Power-Save-Mode Performance in Low-Power Synchronous Buck Converters in TI (Texas Instruments).
Brief:
Buck converters have become common place in a variety of applications where size and efficiency are
primary considerations. While basic converters operate with fixed-frequency, pulse-width modulation
(PWM), many low-power applications can benefit from the performance improvements of variablefrequency
or pulse-frequency modulation (PFM). This topic covers the operational differences between
PWM and PFM architectures, with detailed discussion about key parameters such as output ripple
voltage, quiescent current, and load-transient response. Also covered are PFM topologies that use single
threshold, dual threshold |
