DA9062-10AM, How to regulate voltage in buck1, buck2.

Hello,

I answered question about 'DA9062 default voltage without programming' in the questions below.

Fortunately, i soldered DA9062-10AM in my board not DA9062-00.

I know that DA9062-10AM is pre-programmed chip.

So, i have a some questions.

1.这个芯片(DA9062-10AM)need not programmed OTP right?

2. Then, What is DA9062-10AM default voltage?

3. I inspect the voltage about 1.2v in buck1, 2 when turn on the this chip. But i want to 0v85 like in sch below.

How to regulate voltage in buck1, 2?? -> Could i regulate the voltage by using I2C or other method?

I want to 0v85 not programmed voltage when turn on the device.

Please reply~

谢谢~

Hello,

Hello,

1.That is correct.

2.

Buck 1 is set for 1.0V

Buck 2 is set for 1.35V

Buck 3 is set for 3.3V

buck 4 is set for 1.0V

LDO 1 is set for 3.3V

LDO 2 is set for 1.8V

LDO 3 is set for 1.8V

LDO 4 is set for 2.8V

3. The DA9062 has I2C access for altering the buck/ldo voltage along with other settings.

Kind regards,
Elliott
