TPS76830QPWPRQ1 Datasheet
TPS76830QPWPRQ1 Price Turn-On Time: In the circuit of Figure 4-1, turning Qi on applies a low-voltage to the Inbibit* control (pin l) and disables the output of the regulator 2. If Qi is then turned off, the ISR executes a soft-start power up. Power up consists of a short delay (approx. 2 msec), followed by a period in which the output voltage rises to the full regu- lation voltage. The module produces a regulated output voltage within 10 msec. Figure 4-2 shows the typical rise in both the output voltage and input current for a PT6464 (1.8 V), following the turn-off of Qi The turn off of Qi corresponds to the rise in the waveform, Qi Vds. The waveforms were measured with a 5VDC input voltage, and 8.5-A load. TPS76830QPWPRQ1 on stock 3.1 EXTERNAL RESET At power up, if the internal power up reset worked, all inter- nal latches and flip-flops are cleared and the part is ready to be programmed. The power up state can also be achieved by performing an External Reset, which is required to insure proper operation. External Reset is achieved by asserting ML and DISRFSH for at least 16 positive clock edges. In order to perform simply a Reset, the ML signal must be negated before DISRFSH is negated as shown in Figure 5a. This procedure will only reset the controller which now is ready for programming. The integrated nonlinearity (l NL) is determined by first constructing the least-squares best fit straight line through the delay-versus-address data. The INL is then the deviation of a given delay from this line. For all dash numbers, the INL is within l.0 LSB at every address. |
