TPS54561DPRR

TPS54561DPRR Description
The TPS 534 thermopile sensor in TO 5 type housing employs a chip of 1.2 x 1.2 mm2 absorber size and a 30 kV thermistor as temperature reference.
The round window opening is equipped with a 5.5 µm longpass (standard) infrared filter.
The sensor shows a flat sensitivity characteristics over the wavelength.
The TPS54561 is a 60-V, 5-A, step down regulator with an integrated high side MOSFET.
The device survives load dump pulses up to 65V per ISO 7637.Current mode control provides simple external compensation and flexible component selection. Alow ripple pulse skip mode reduces the no loadsupply current to 152 A. Shutdown supply current is reduced to 2 A when the enable pin is pulled low.Undervoltage lockout is internally set at 4.3 V but can increase using an external resistor divider at the enable pin.
The output voltage start up ramp is controlled by the soft start pin that can also be configured for sequencing/tracking. An open drain power good signal indicates the output is within 93% to 106% of its nominal voltage. A wide adjustable switching-frequency range allows for optimization of either efficiency or external component size. Cycle-by-cycle current limits frequency foldback and thermal shutdown protects internal and external components during an overload condition.
The TPS54561 is available in an 10-pin 4-mm x 4mm WSON package. TPS54561DPRR
