This DCDC IP is a high efficiency PWM step-down DC/DC converter IP,
with fast transient response and accurate regulation. Both the main (P-Channel MOSFET) and
synchronous (N-Channel MOSFET) switches are internal.
It provides PWM mode and PFM mode that can be automatically switched. The converter operates
on PWM mode with 70mA or higher load current. Lighter load current causes it automatically
switching into PFM mode.
It has a significant advantage to generate ultra-low ripple output. While using the external
capacitors with low ESR resister, the ripple voltage is as low as 5mV or below. The performance
makes the converter suitable for RF applications.
It has another important advantage to provide output with fast transient
