... DETAILED DESCRIPTION VOLTAGE REFERENCE A 2.5-V regulator operating from Vcc is used to power the internal circuitry of the TL5001 and as a reference for the error amplifier and SCP circuit. A resistive divider provides a 1-V reference for the error amplifier non-inverting input which typically is within 2% of nominal over the operating temperature range. ...

... DTC is derived by the following equation: If the dc-to-dc converter must be in regulation within a specified period of time, the time constant, RDTCDT, should be t0/3 to t0/5.The UTC TL5001 remains off unit VDT≈0.7V, the minimum ramp value. CDT is discharged every time UVLO or SCP becomes active. ...

... OUTPUT TRANSISTOR The output of the UTC TL5001 is an open-collector transistor with a maximum collector current rating of 21mA and a voltage rating of 51V.The output is turned on under the following conditions: the oscillator triangle wave is lower than both the DTC voltage and the error-amplifier output voltage, the UVLO circuit is inactive, and the short-circuit protection circuit is inactive ...
