The TPS4005x is a family of high-voltage, wide-input (8 V to 40 V), synchronous, step-down controllers. The TPS4005x family offers design flexibility with a variety of user-programmable functions, including soft start, UVLO, operating frequency, voltage feedforward, high-side current limit, and loop compensation.

The TPS4005x uses voltage feedforward control techniques to provide good line regulation over the wide (4:1) input voltage range, and fast response to input line transients. Near-constant modulator gain with input variation eases loop compensation. The externally programmable current limit provides pulse-by-pulse current limit, as well as hiccup mode operation using an internal fault counter for longer duration overloads.

The new products, LM5145 and LM5146, offer reduced BOM cost, higher efficiency, and reduced solution size among many other features. Start a WEBENCH design with LM5145 and LM5146.

TPS40055EVM-001 — Evaluierungsmodul wandelt 12 V Bus in 1,8 V bei 15 Amps

In many modern electronic applications there is a growing demand for circuits to convert a12-V bus to digital voltages as low as, but not limited to 1.8 V. The current requirements can range from below 1 A to over 15 A. For high-efficiency and small circuit size the TPS40055 wide-input synchronous (...)

TPS40055EVM-002 — Wandler mit großem Eingangsbereich liefert 5V A bei 2 A.

The TPS40055EVM−002 wide range input dc-to-dc converter uses the TPS40055 synchronous rectifier controller to step down a 10-V to 40-V input to 5 V. The output current is 3 A with an input of 10 V and should be linearly derated to 2 A at VIN = 40 V. The TPS40055 is used because it offers a variety (...)
