Part Number: LM51770 Hi :
In my case, I use LM51770 to output 12VSB with a 19V adapter. When adapter is connected with the motherboard, there is a unexpected output behavior happened and then LM51770 will successfully provided a 12V output voltage after…
Part Number: LM51770 Hello,
I am using this part to design a power supply, and I am trying to calculate the compensation gain resistor following the Equations (3) and (46) in the Datasheet:
The value of the current sense amplifier gain A_CS, is…

Hello,
When calculating the UVLO divider according to Section 9.2.2.8 of the Datasheet, I am getting different results from the stated target UVLO voltage. The Datasheet states: "Design the UVLO resistor divdier for turn-on below…
Part Number: LM51770 Hello,
When calculating UVLO resistors from the datasheet and the spreadsheet calculator, they produce different results. My target UVLO is with a 17.9V turn-on voltage and a 16V turn-off voltage. Using the datasheet equations,…
Part Number: LM51770 I have a power supply intended for use with Li-Ion 8S1P (30V nominal) battery to 24V at 8 to 15A motor supply. I used the Design Spreadsheet as recommended by the TI support staff. I'm having trouble getting it to regulate properly…
Part Number: LM51770-Q1 Bonjour TI,
Configuration de mon convertisseur :
Vin = 24V - 32V
Vout = 12V - 40V (modulable)
Charge = 6.66Ohms (courant compris entre 1,8A et 6A).
J'ai ma charge qui varie de 0 à 6A maximum avec une fréquence de…
Part Number: LM51770 Other Parts Discussed in Thread: LM5177EVM-HP I have created a PCB based on the schematic of the LM5177EVM datasheet.
Since my requirements are slightly different, I bought a development board and modified it using the same values…
Part Number: LM51770-Q1 Other Parts Discussed in Thread: LM51770 Hi TI,
I have a 250W buck-boost converter with the following specifications:
Vin: 18V – 32V
Vout: 40V, 28V, or 12V
Frequency : 1MHz.
Load: 6.25 ohms
I'd like to know the…
Part Number: LM51770 Hello,
I need an information about the maximum sourcing and maximum sinking current of the COMP-Pin of LM51770. The datasheet indicates only min and typ values. I will connect an OPA-regulator to this pin in order to overwrite the…
Part Number: LM51770 Hi There
I designed a Buck-Boost PSU using the LM51770. The intent was to be able to generate 12V (+/- 1V) at 14A with a wide input of 6-60V. Please see schematic below. The unit works from 5.6V and turns off at 5.3V so the UVLO…
