LT8349ACBZ: 8V, 12A, Two Phase Low IQ Synchronous Boost Converter, WLCSP-35

Basic Information:

Model Number: LT8349ACBZ

Package: WLCSP-35

Type: Synchronous Boost Converter

Overview:

The LT8349ACBZ is a two-phase, single-output synchronous boost converter capable of driving two internal N-channel power MOSFET stages in a non-in-phase manner. Multi-phase operation reduces input and output capacitor requirements and allows the use of smaller inductors than their single-phase counterparts. Synchronous rectification improves efficiency, reduces power losses, and lowers heat dissipation requirements, enabling high-power boost applications.

LT8349ACBZ - Product Attributes:

Input voltage range: 2.5V to 5.5V 

Output voltage programmable to 8V

2-phase operation reduces required input and output capacitance and power supply inductive noise

Synchronous operation for high efficiency and reduced heat dissipation

Stage SheddingTM and optional Burst Mode® operation modes for efficient operation at light loads

Low VIN pin quiescent current:

0.5µA at shutdown 

15µA in Burst Mode operation

Integrated 8V/6A synchronous power switch

Adjustable and synchronisable: 300kHz to 4MHz

Burst mode or forced continuous operation at light loads

Precise 1V enable pin thresholds

Small 1.9mm x 2.6mm WLCSP package

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
