TNPW12061003FT9RT1 Datasheet
TNPW12061003FT9RT1 Price FUNCTIONAL DESCRIPTION This 5-bit shift register is composed with 4 R-S-T flip-flops and it functions as a serial/parallel inpput-serial/parallel output shift register. For use as a *serial input-serial/parallel output shift register, the load input LOAD or parallel data inputs SDO--S04 are kept in high and the data are applied to the serial data input Ds. When a clock pulse is applied to clock input T with Ds in high, the high signal is shifted sequentially to Oo, Oi ... 04. Shifting is performed when T changes from low to high. When the serial data are applied to Dso~SD4 and LOAD is set high, the SDo~SD4 signals appear in OO~Q4 respectively irrespective of T. When direct reset input RD is set low, 00~04 are set low if LOAD is low irrespective of the other input signals. When LOAD is high, parallel reading takes precedence, and the SDo~SD4 signals appear in ooQ4. TNPW12061003FT9RT1 on stock When the input voltage reaches the detection voltage, the output goes low. This detection voltage has a +? % accuracy and is set at the factory. When the input voltage goes high, the output will staylow until the voltage reaches the detection voltage plus hysteresis (+3 to +7 %). The maximum duty cycle under boost mode is internally limited t0 70% to prevent inductor saturation. If the converter is turned on for 100% duty cycle, inductor never gets a chance to discharge its energy and eventually saturate. In boost mode, synchronous rectifier is always turned on for minimum or greater duration as long as the switch has been turned on. The controller will deliver 0% duty cycle, if the input voltage is greater than the programmed output voltage. Because of signal propagation time and MOSFET delay/rise/fall time, controller will not transition smoothly from minimum controllable duty cycle t0 0% duty cycle. For example, controller may decrease its duty cycle from 5% t0 0% abruptly, instead of gradual decrease you see from 70% t0 5%. |
