Texas Instruments LM5141-Q1 | Demoboard LM5141QRGEVM
LM5141QRG Synchronous Buck Converter Evaluation Module
Details
| Topologie | Abwärtswandler |
| Eingangsspannung | 5.5-42 V |
| Schaltfrequenz | 2000-2400 kHz |
| Ausgang 1 | 5 V / 5 A |
Beschreibung
The LM5141-Q1 is a synchronous buck controller,intended for high voltage wide VIN step-downconverter applications. The control method is basedon current mode control. Current mode controlprovides inherent line feed-forward, cycle-by-cyclecurrent limiting, and ease of loop compensation. TheLM5141-Q1 features slew rate control to simplify thecompliance with the CISPR and Automotive EMIrequirements.The LM5141-Q1 has two selectable switchingfrequencies, 2.2 MHz and 440 kHz, and Gate Driverswith Slew Rate Control, for reduced conducted EMI.
Eigenschaften
The EVM supports the following features and performance capabilities:
- The LM5141-Q1 is Qualified to AEC-Q100 Grade 1 (–40ºC to +125ºC Operating JunctionTemperature)
- VIN 5.5 to 42 V
- Fixed 5-V output, or Adjustable From 1.5–15 V
- Shutdown mode IQ: 10 μA
- Low IQ Standby: 42 μA Typical (Output in Regulation, No Load)
- Fixed 2.2 MHz, or 440 kHz Oscillator Frequency
- Oscillator Can Shift From the Fundamental With a Resistor From the RT Pin to Ground, or an Analog
- Voltage of 0 V to 0.6 V
- The Internal Oscillator can be Synchronized to an External Clock
- Spread Spectrum
- EN Enable Output
- Hiccup Mode for Sustained Overload
- Power Good
- Gate Drive With Slew Rate Control
- Diode Emulation or Forced Pulse-Width Modulation
