LP87702: PMIC Recommendation Inquiry

Part Number: LP87702

Tool/software:

Hi, TI expert

The customer is looking for a PMIC that satisfies the following specs.

The purpose is to reduce DC/DC or LDO of other parts of the circuit, not a PMIC to connect to the processor or MCU.

- Input voltage_3.7V Battery: Vin min 3.0~ Vin Max 4.2V
- Output voltage 1: Boost 5V, 1.5A
- Output voltage 2: Buck 3.3V, 0.5A
- Output voltage 3: Buck 1.8V, 0.1A
- Output voltage 4: Boost 13V, 0.3A

Can you recommend a suitable PMIC?
If there is no PMIC that satisfies all of them, please check if there is a PMIC that satisfies except for Output voltage 4 (Boost 13V, 0.3A).

Please check. Thank you.

  • Hi,

    I didn't find any that could fit above requirement because of BOOST high current requirements. In most PMICs, the boost current ranges upto 0.6 mA or less than 1 A. 

    You may need to go for discrete solution for the BOOSTs and dual buck for 3.3V and 1.8V rails.
