Part Number: LM5164 Hello - We are designing a negative voltage supply using LM5164 and not sure where to connect (or not connect) the exposed paddle of LM5164.
The datasheet of LM5164 states that the exposed paddle (EP) pin of LM 5164 has "no internal…
Part Number: LM5164-Q1 Other Parts Discussed in Thread: LM5164 hi expert
For the LM5164 power chip, if the external circuitry of the power input Vin does not use a reverse voltage protection diode (which is necessary for low-voltage startup and to reduce…
Part Number: LM5164LM5164DDAR getting damaged during Functional circuit test We are using the LM5164 as a buck regulator in our IoT device, designed for 9-90V input and +5V output. Issue: As the production of the devices has started, we are observing…
Part Number: LM5164 Other Parts Discussed in Thread: LM5163 TINA-010208 as a REFERENCE circuit diagram I designed the circuit diagram of LM5163 and applied LM5164 for the actual parts. The LM5164 is currently experiencing a RINGING phenomenon. What debugging…
Part Number: LM5164
Hi,
We configured the circuit as shown in the schematic above. Out of 10 assembled boards, 2 boards exhibit audible noise coming from the input MLCCs. The PCB artwork was designed according to the reference layout in the datasheet…
Part Number: LM5164 Hi Team,
Posting on behalf of our customer.
I'll share this E2E post with our customer so he can reply when needed.
Could you help with the LM5164 schematic?
In our project, the LM5164 is used to generate 5V and 3.3V. The 5V…
Part Number: LM5164-Q1 Hi team,
A PCN notice has been issued for the LM5164-Q1.
Are the recommended thermal pad land patterns the same before and after the PCN?
Since the size of the thermal pad itself will change, should the land pattern be adjusted…
Part Number: LM5164 Tool/software: Hi,
I am using the LM5164 buck converter.
Vin = 48V nominal (30V-57V)
Vout = 10.3V
Iout max = 0.1A
Freq = 250kHz
L = 100uH
When i decrease the load to ~0.3mA i see the following spike in the SW pin:
