Texas Instruments Buck Converter for LMR14030

Three evaluation modules from Texas Instruments to demonstrate the performance of the LMR14020, LMR14030 & LMR14050 Simple Switcher® devices. These step-down (Buck) converters operate with a wide input voltage range and provide output currents of up to 5A whilst having a low quiescent current of only 40 μA. The output voltage of the modules is jumper-selectable at 3.3 or 5V.

The three module options are as follows:
903-3781 LMR14020SEVM Maximum output current 2A, switching frequency 1.6 MHz
903-3790 LMR14030SEVM Maximum output current 3.5A, switching frequency 600 kHz
903-3787 LMR14050SEVM Maximum output current 5A, switching frequency 400 kHz

• 4 to 30V Input voltage range
• Output voltage 3.3 or 5.0V (Jumper selectable)
• Up to 2/3.5/5 A output current
• Low 40 μA quiescent current
• Internal Compensation
