Harmeet Singh

Part Number: TPS62745

Hi Team,

One of my customers is looking for a part similar to TPS62745 in features with only change being the selectable output voltage range.

In TPS62745, selectable output voltage range is 1.8-3.3V.

customer requirement for output voltage range is 2.5-4.0V. The output voltage needs to be selectable using VSEL pins with resolution of 0.1V.

Specifications:

Input Voltage Range V_IN from 3.3 V to 10 V
Typical 400 nA Quiescent Current
Up to 90% efficiency with load currents >15 µA
Up to 300 mA Output Current
RF Friendly DCS-Control™
Low Output Ripple Voltage
16 Selectable Output Voltages from

2.5 V to 4.0 V

Integrated input voltage switch
Integrated Discharge Function at VOUT
Open Drain Power Good Output
Operates with a Tiny 3.3 µH or 4.7 µH Inductor
Small 3 mm × 2 mm WSON Package

Can you suggest the closest part which can meet these specifications?

Regards,

Harmeet

Hi Harmeet,

Thanks for reaching out to us.

The set of features you are listing is quite broad.
In order to help you better, may I ask you for the application of the device needed and which parameters are the most valuable in these features required?

Thanks!
Omar

Hi Omar,
As per me the important parameters are output voltage selectable from 2.5 to 4.0V through vsel pins and the very low quiescent current as the application will be battery operated may be water or gas meter.

Regards,
Harmeet

Hi Harmeet,

I do not think that there is a better matching part for this set of specs than the TPS62745. I will close this thread and I will discuss this with you offline to get more details!

Thanks!
Omar
