• ### ADP1850 current sense gain calculation

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…

• ### ADP1850 in parallel for HIGH current

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 Current limit resistor

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 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…

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…

• ### RE: ADP1876 parallel operation

Hi Aravind,

The simplest way would be adding bleeder resistor to the output.

You can also do a 4-phase operation by adding a multiphase oscillator like LTC6902 and connect the outputs to SYNC of each ADP1850. You can also simulate 4-phase operation in…
