LM3150-250EVAL/NOPB

| Evaluation Board for LM3150-250 kHz - SIMPLE SWITCHER® CONTROLLER, 42V Synchronous Step-Down | Full production Lead Free (RoHS)
|
| $29.00 each | 1 |
Description:
The LM3150 evaluation boards are designed to provide the design engineer with a fully functional power converter based on Constant On-Time with Emulated Ripple mode control to evaluate the LM3150 and the entire LM315x family of parts. The evaluation board is preconfigured to use the LM3150 with the output voltage adjusted to 3.3V, with a typical max load current of 10A. This board is configured for 250 kHz. The printed circuit board consists of 4 layers of FR4 material and the top and bottom layers using 2 once copper and the inner layers using 1 once copper. The board size is 2.9” X 2.9”.
The evaluation board allows for a variety of configurations, and this multifunctional capability is used to also accept the fixed ouput versions of the LM3150 such as the LM3151-3.3, LM3152-3.3, and LM3153-3.3.
Features:
- Switching Frequency: 250 kHz
- Input Voltage Range: 6V to 42V
- Output Voltage: 3.3V
- Output Current: 0A to 10A

LM3152-3.3DEMO
| LM3152 - RD-164 - Demonstration Board | Full production
|
| $19.00 each | 1 |
| Description:
The LM3152-3.3 demonstration board is a part of the PowerWise® family of SIMPLE SWITCHER® Controllers. It has been designed to balance solution size and performance. The Constant-On-Time (COT) Emulated Ripple Mode (ERM) Control allows for the use of low ESR output capacitors and therefore decreases the output voltage ripple while maintaining a fast transient response. There is no loop compensation required for the COT architecture , as there is in voltage-mode and current mode control architectures, which helps to facilitate the ease of design and fast transient response. The demoboard uses a 2-layer , 2 ounce copper PCB with all of the components mounted on the top side. The LM3152-3.3 IC has a fixed output voltage of 3.3V and will operate over the input voltage range of 6V to 24V at 10A load current.
Features:
- Easy To Use with Webench and Offline Design Tools
- No Loop Compensation Required
- Low Solution Component Count
- Ultra-Fast Transient Response
- Low Output Voltage Ripple (32mVpp)
- 3.3V Fixed Output Voltage
- Optimized for 10A Average Load Current
- 95% Peak Efficiency
- Constant-On-Time with Emulated Ripple Mode Control
- 500 kHz Switching Frequency

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
