評估模組將 12V 匯流排轉換為 1.8V (15A)
TPS40055EVM-001
概覽
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 buck controller can be used to provide the necessary control and drive functions to implement these converters. The TPS40055EVM−001 operates at 300 kHz and delivers 1.8 V at 15 A with efficiency over 90% for much of the load range, and a full load efficiency of 88%.
The TPS40055 synchronous buck controller offers a variety of user programmable functions such as operating frequency, soft-start time, voltage feed-forward, high-side current limit, and external loop compensation. This controller also provides a regulated 10-V bias voltage which supplies onboard drivers for the N-channel switch and synchronous rectifier MOSFETs, utilizing adaptive gate drive logic to prevent cross conduction of the power MOSFETs.
