TPS2202Y Datasheet The DAC2800D series of DC-DC converters share load fault philosophies. Load fault conditions include short-circuit and severe overload conditions. The DAC2800D converter series responds to load faults by turning off all power conver- sion circuits for 250 mS and then attempting to restart for 10 mS (typical). The net "on" duty factor during a fault is very low resulting in low converter dissipation and immunity from overheating at 1250C. Current beyond rated can flow into the load at startup time. This allows the converter to bring up capacitive and other difficult load types more reliably than competing converters. TPS2202Y Price
TPS2202Y on stock FEATURES , Output Accuracy SV, 3.3V@ 350mA Output ~ Very Low Quiescent Current . Low Dropout Voltage . Extremely Tight Load And Line Regulation ' Very Low Temperature Coefficient . Current & Thermal Limiting . Error Flag Warns Of Output Dropout . Logic-Controlled Electronic Shutdown . Output Programmable From l.24V t0 29V part go into the hysteretic mode with both the high and low side switches off. The output voltage starts to drop until it hits the low threshold of the hysteretic comparator, and the part immediately goes back to the PWM operation. The output voltage keeps increasing until it reaches the top hysteretic threshold, then both the high and low side switches turn off again, and th same cycle repeats. |
