DescriptionThe TPS40057PWPR is designed as one member of the TPS4005x family which is of high-voltage, wide input (8V to 40V), synchronous, step-down converters. This TPS40057PWPR offers design flexibility with a variety of user programmable functions, including soft-start, UVLO, operating frequency, voltage feed- forward, high-side current limit, and loop compensation. Applications of TPS40057PWPR include power modules, networking / telecom, industrial and servers.
TPS40057PWPR has many features. (1) Operating input voltage is from 8V to 40V. (2) Input voltage feed-forward compensation. (3) < 1% internal 0.7V reference. (4) Programmable fixed frequency up to 1MHz voltage mode controller. (5) Internal gate drive outputs for high-side and synchronous N-channel MOSFETs. (6) 16-pin powerPAD package (JC=2°C/W). (7) Thermal shutdown. (8) Externally synchronizable. (9) Programmable high-side current limit. (10) Programmable closed-loop soft-start. (11) Source / sink with Vout prebias. That are all the main features.
Some absolute maximum ratings of TPS40057PWPR have been concluded into several points as follow. (1) Its input voltage range would be 45V for Vin and would be from -0.3 to 6V for VFB, SS, SYNC and it would be from -0.3V to 45V for SW and would be -2.5V for SW, transient < 50ns and it would be from -0.3V to 11V for KFF, with Iin(max)=-5mA. (2) Its output voltage range would be from -0.3V to 6V. (3) Its input current would be 5mA. (4) Its output current would be 200uA. (5) Its operating junction temperature range would be from -40°C to 125°C. (6) Its storage temperature would be from -55°C to 150°C. (7) Its lead temperature 1,6mm (1/16 inch) from case for 10 seconds would be 260°C.
And also some electrical characteristics about TPS40057PWPR. (1) Its input voltage range would be min 8V and max 40V. (2) Its quiescent current would be typ 1.5mA and max 3.0mA. (3) Its output voltage would be min 4.7V and typ 5.0V and max 5.2V. (4) Its accuracy would be min 470kHz and typ 520kHz and max 570kHz. And so on.
