Part Number: LM51770 Hi Teams,
The customer is using LM51770 for robot power board design. Please help confirm if the schematic is reasonable. Thank you~ LM51770_Buck-Boost_Quickstart_Tool_V1_0_1.zip
Part Number: LM51770 Hello TI,
Regarding the choice of MOSFET, should we select one for a 10V or 5V gate capacitor? You specify a Vbias of 12V, but I assume that refers to the LM51770.
Vu que le MOSFET est piloté en 5V, je serais tenté de prendre…

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 Other Parts Discussed in Thread: UCC27302A
I use LM51770 in HOx_LL external gate driver mode. HOx_LL and LOx are ground-referenced logic PWM signals feeding two UCC27302A. HB1/SW1 and HB2/SW2 each have a 100nF bootstrap capacitor…
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…
