I am using ADP5052 to power altera cyclone v gx,
1) CH1 and CH2 does not turn ON when switching frequency is less the 850KHz. (CH3 and CH4 workes without any problem)
2) switching frequency resistor value changed to 24.3K, CH1 and CH2 turned on but the output expected voltage is not met.
3) when i connect CH1 and CH2 to a small load i.e 50mA, the regulators gets latched off and the output is disabled.
i tried changing the compensation RC values and also set the PMIC to Automatic PWM/PSM Modes but no luck. please help.

Thank you for your replay!
After re mounting the ADP5052 it started working fine. so it was soldering issue.
