MAXREFDES1274: 5V, 500mA step-down converter using the MAX17501F

MAXREFDES1274: 5V, 500mA Buck Converter using the MAX17501F

Overview

The MAXREFDES1274 is a buck converter using the MAX17501F high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs and internal compensation. This design produces a 5V output at up to 500mA from a wide input range of 6.5V to 60V. The device features peak-current-mode control with pulse-width modulation (PWM). The MAXREFDES1274 was optimized for small solution size and is laid out on a two-layer PC board.

Six points to note when maintaining and servicing LED displays
[hide]1. The display should also be used in a balanced way. 　　Since the basic display principle of LED backlight display is the same as that of traditional CCFL backlight display, both rely on the bac
STM32 software brake stops PWM
Why after I use software brake to stop PWM, the IO pin still has output and the status of the IO pin is uncertain? I use the multiplexing function of IO. . . . . . . . . . . But the hardware brake tha
About the driver development environment setting up
This question may be very old, but it is a big problem for us novice developers. Many enthusiastic young people gave up because of the frustration caused by the development environment. First of all,
Urgent! ! The IImage interface in wince can only display jpg images of about 1.5M in size. I want to display larger images. What should I do?
Can any expert who has encountered this situation give me some advice? I'm so anxious!
