Overview
...nt off−line fixed frequency current−mode control with a minimum number of external components.
The CS52843 incorporates a new precision temperature−controlled oscillator to minimize variations in frequency.
An undervoltage lockout ensures that VREF is stabilized before the output stage is enabled.
In the CS52843 turn on is at 8.
4 V and turn off at 7.
6 V.
Other features include low start−up current, pulse−by−pulse current limiting, and a high−current totem pole output for driving capacitive loads, such as gate of a power MOSFET.
The output is low in the off state, consistent with N−channel devices.
