Pin # Symbol Pin Description 1 SHD Device is placed in shutdown when SHD is driven low. In shutdown mode, the internal MOSFET and output are turned off. Driven to high for normal operation. This pin is floating internally and needs to be tied to a fixed source externally. 2 SYN External Synchronization Clock Signal Input. If a clock signal is pre.
include thermal shutdown with hysteresis and cycle−by−cycle current limit in the PWM mode. Additionally, the converter transitions into PFM mode at very light loads if a synchronization signal is present and an output overvoltage condition is detected.
