600 MA PWM/PFM Step-Down Converter With External Synchronization Pin

The NCP1530 is a PWM/PFM nonsynchronous stepdown (Buck) DCDC converter for usage in systems supplied from 1cell Liion, or 2 or more cells Alkaline/NiCd/NiMH batteries. It CAN operate in ConstantFrequency PWM mode or PWM/PFM mode in which the controller will automatically Switch to PFM mode operation at low output loads to maintain high efficiency. The switching frequency CAN also be synchronized to external Clock between 600 kHz and 1.2 MHz. The maximum output current is up to 600 mA. Applying an external synchronizing signal to SYN pin CAN supersede the PFM operation. By ON Semiconductor
