General Description
APW7336 is a 2A synchronous buck converter with inte grated power MOSFETs. The APW7336 design with a cur rent-mode control scheme, can convert wide input volt age of 4.5V to 24V to the output voltage adjustable from 0. 8V to 20V to provide excellent output voltage regulation.
The APW7336 is equipped with an automatic PFM/PWM mode operation. At light load, the IC operates in the PFM mode to reduce the switching losses. At heavy load, the IC works in PWM.
