EXT 1 /

PWM/PFM Switching Pin <PWM control when connected to VDD, PWM / PFM auto switching when connected

to Ground. >

Chip Enable Pin <Connected to Ground when output is stand-by mode. Connected to VDD when output is

active. EXT/1 is high and EXT2/ is low when in stand-by mode.>

Synchronous / Non-Synchronous Rectification Switching Pin <Synchronous operation when MODE pin and

PWM pin are connected to VDD, Non-Synchronous operation when MODE pin and PWM pin are connected to

Ground. Regardless of MODE pin, Non-Synchronous operation when PWM pin is connected to Ground.

Output Voltage Monitor Feedback Pin <Threshold value : 0.9V. Output voltage can be set freely by connecting

split resistors between VOUT and Ground.>
