Description

The TPS40055PWP is designed as one member of the TPS4005x family of high-voltage, wide input (8 V to 40 V), synchronous, step-down converters. The TPS4005x family 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. Typical applications include power modules, networking / telecom, industrial and servers.

TPS40055PWP has ten features. (1) Operating input voltage would be 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. That are all the main features.

Some absolute maximum ratings of TPS40055PWP have been concluded into several points as follow. (1) Its input voltagr range would be 45V for VIN and would be from -0.3V to 6V for VFB, SS, SYNC and would be from -0.3V to 45V for SW and would be -2.5V for SW, transient < 50ns and would be from -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 range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics about TPS40055PWP. (1) Its input voltagr 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. And so on. If you have any question or suggestion or want to know more information of TPS40055PWP please contact us for details.
