Description: High Frequency Power Supply Controller

Features

* not found on the 3823. These features are set in italics. FEATURES s s s s s s s s s s s s s Practical operation at switching frequencies to 1.0MHz High current (2A peak) totem pole output Wide bandwidth error amplifier Fully latched logic with double pulse suppression Pulse-by-pulse current limit

Applications

* using voltage or current mode and provides for input voltage feed forward. A 1V threshold current limit comparator provides cycleby-cycle current limit and exceeding a 1.4V threshold initiates a soft-start cycle. The soft start pin doubles as a maximum duty cycle clamp. All logic is fully latched to
