OVERVIEW AND GENERAL OPERATION

The chip is a fixed frequency Pulse Width Modulator based on the industry standard UC1843x Series with significant

enhancements in performance and functionality. The chip operates in either the voltage or current mode and can support a wide

variety of converter topologies.

Radiation hardened by design techniques ensure the chip’s outstanding radiation tolerance (>1MRads) while reducing operating

current by more than an order of magnitude over comparable parts.

The PWM5031 provides an under voltage lockout feature with hysteresis that also provides an output to indicate Power is OK.

An input called Sleep is used to power down the entire chip, the Enable input is used to shut down the Oscillator / Output Drives,

and the Soft input drives the Output to zero. There is also a signal input called ENAUX that is used to disable the output to the

auxiliary op-amp.

The dual output drivers are designed using a Totem Pole output capable of sinking and sourcing 50mA constant current and peak

currents up to 1 Amp to support a large variety of Power MOSFETs.

Additional features that boost the appeal and utility of the part are:

◆

Dual break-before-make Totem Pole output stage is employed that virtually eliminates cross conduction and current shoot

through

◆

Logic level input that allows the user to select either 50% or 100% maximum duty cycle operation

◆

Improved oscillator stage that vastly increases waveform linearity and reduces output voltage error

◆

Uncommitted on-board op-amp which can be used for signal conditioning, pulse feedback, or any other user defined

purpose
