Dear Analog Device Team

In our present design, We are using ADP1850 

As per the reference schematics, there are two grounds AGND and PGND, which are shorted.

In the reference layout, there are no separate grounds.found.

In our design, we have isolated…

I am having trouble getting the correct value for the current limit resistor.  Based on the formula on the datasheet (page 16) the resistor should be increasing with increased output current but experimentally in Ltspice I have found the reverse to be…

Dear All:

I read "AN-1119-Printed Circuit Board Layout Guidelines for Step-Down Regulators..." documents have some question, would like to ask ADP1850/ADP1851 the thinnest 4-layer PCB Board thickness how much? 1.6mm feasible? ADP1850/ADP1851 demo board…

Hey All,

I am struggling to calculate the Rcsg resistor for the ADP1850. Probably using ohms law all i have from the datasheet is the voltage only which is 0.4 and 2.1. I have the Vcsmin and Vcsmax at 0.66 and 1.206 respectively. The Rramp is calculated…

Hey All,

I have requirement for stepping down a 12v 82A power supply to 8.1V and limit current to 80A. I seen ADP1850 eval board that uses this to achieve 50A. Can this be done by adding another ADP1850 in parallel sharing the same Vin and Vout Or is…

ADP1850, ADP1877 and ADP1829 are all dual channel buck regulator controllers. What are some of the key differences between these three?

Dear Analog Device Team

In one of our design, we are planning to use ADP5003 and ADP1850 as per the block diagram attached.

In this system, we are using three regulators 

Regulator 1 : ADP1850 (12V INPUT, 5V,3.3V OUTPUT)

Regulator 2 : ADP1850 (12V INPUT…

Dear All:

请问一下ADP1850/ADP1851 外部的DL/DH MOSFET为什么需要各摆2颗MOSFET,主要用途为何?为什么需要DL/DH需要各摆2颗?就以ADP1850的BSC0902NS MOSFET来说"ID=100A"已经可以满足需求了,为何还要各摆2颗MODEFET,如果我有空间上元件摆件空间的问题,我可以DL/DH可以各摆1颗MOSFET就可以吗?
