Article as decribed , yet the operating system and computer sees it however it sees no STM i used what i was able to find on information about what wire needs to be where. As this item is slightly different and the SWIM only make sense to the initiated could you please share the way it should be wired to MINI JTAG and other commonly used iterfaces AS SWD ?

I bought 5 pcs, went for a long time. The view is better than the last time (then all 5 were actually inoperable without replacing capacitors, chokes and chip!!!!!) -capacitors are thicker in appearance and on the throttle there is a marking-100, which, apparently, means 10 μh. Later, after checking, i will add a review.

LM5176RHFR 描述

***as Instr.: The LM5176 is a synchronous four-switch buck-boost DC/DC controller capable of regulating the output voltage at, above, or below the input voltage. The LM5176 operates over a wide input voltage range of 4.2 V to 55 V (60-V absolute maximum) to support a variety of applications.

***AS INSTRUMENTS INCORPORATED: The LM5176 uses current-mode control both in buck and boost modes of operation for superior load and line regulation. The switching frequency is programmed by an external resistor and can be synchronized to an external clock signal.

***AS INSTRUMENTS INC: The device also features a programmable soft-start function and offers protection features including cycle-by-cycle current limiting, input undervoltage lockout (UVLO), output overvoltage protection (OVP), and thermal shutdown. In addition, the LM5176 features optional average input or output current limiting, optional spread spectrum to reduce peak EMI, and optional hiccup mode protection in sustained overload conditions.
