... IN SYNC FUNCTION When the SYNC pin is high, PSM is deactivated. The ADP2503/ ADP2504 always operate in PWM using the internal oscillator. When the SYNC pin is switching in the 2.1 MHz to 2.9 MHz range, quency applied on SYNC and then locks on it. When the SYNC pin stops switching, the regulator switching frequency slides back to the internal oscillator frequency ...

... If the ADP2503/ADP2504 are operating in buck mode, the worst-case voltage ripple occurs for the highest input voltage the ADP2503/ADP2504 are operating in boost mode, the IN worst-case voltage ripple occurs for the lowest input voltage, V The maximum voltage overshoot, or undershoot, is inversely proportional to the value of the output capacitor. To ensure stability and excellent transient response recommended to use a minimum of 22 μ ...
