EUP2539 10 White LED Boost Converter In Thin TSOT-23 Package
... white LEDs, so the LED currents are identical for uniform brightness. The EUP2539 switches at 1MHz, allowing the use of tiny external components. The output capacitor can be as small as 0.22µF, saving space and cost versus alternative solutions. A low 0.3V feedback voltage minimizes power loss in th ...

Test probe
A test probe (test lead, test prod, or scope probe) is a physical device used to connect electronic test equipment to a device under test (DUT). They range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile.
