Supply LTC3401EMS Step Up DC DC Converter, Supply ADI Synchronous Boost Converter

Shenzhen Mingjiada Electronics Co., Ltd. — as a professional electronic component supplier, maintains long-term stock of the LTC3401EMS series, providing customers with genuine chips.

01 Product Overview
The LTC3401EMS is a high-efficiency, fixed-frequency, step-up DC/DC converter manufactured by Analog Devices. This device utilises an MSOP-10 package and integrates power switches and synchronous rectifiers onto a single chip.
The LTC3401EMS operates reliably at input voltages below 1V, with a typical start-up voltage of just 0.85V, making it highly suitable for battery-powered applications.
Its unique synchronous rectification architecture enables high-efficiency conversion without requiring an external Schottky diode (when VOUT < 4.3V), significantly reducing the number of external components and overall solution footprint.

02 Detailed Specifications
The LTC3401EMS's specifications demonstrate its advantages in portable device power management:
Input voltage range: 0.5V to 5.5V, covering diverse battery configuration requirements
Output voltage range: Adjustable from 2.6V to 5.5V, meeting most portable device power demands
Output current capability: Switch-rated current of 1A provides ample power delivery
Switching frequency: Typically 2MHz, programmable up to 3MHz via an external timing resistor
High-frequency operation permits the use of smaller external components, further reducing PCB footprint.
Efficiency: Up to 97%, maximising battery life
Quiescent current: Just 38μA in burst mode, delivering extremely low standby power consumption
Operating temperature range: -40°C to 85°C, suitable for diverse operating environments
Package: MSOP-10, occupying minimal board space

03 Product Feature Analysis
The LTC3401EMS incorporates multiple advanced features that distinguish it from competitors:
High-efficiency synchronous architecture
The LTC3401EMS integrates an internal 0.16Ω N-channel MOSFET switch and a 0.18Ω P-channel synchronous rectifier.
This integrated design eliminates the need for external Schottky diodes (when VOUT < 4.3V), reducing system cost while enhancing overall efficiency.
Flexible Power Management
The LTC3401EMS offers Burst Mode operation, controlled by the user via the MODE/SYNC pin.
When Burst Mode is enabled, the device's quiescent current is only 38μA, significantly reducing power consumption at light loads and maximising battery life in portable applications.
Low Noise and High Stability
The LTC3401EMS incorporates anti-ring control to effectively reduce switching noise.
The device also integrates OPTI-LOOP® compensation technology, allowing optimised transient response and enhanced system stability.
Power Good Indication
The LTC3401EMS provides a PGOOD output signal to indicate whether the output voltage is within the normal range, enhancing system reliability.

04 Application Areas
The unique characteristics of the LTC3401EMS enable it to excel in multiple domains:
Portable Communication Devices
The LTC3401EMS is extensively employed in cordless telephones, wireless mobile phones and similar equipment.
Its high efficiency and low quiescent current properties significantly extend the operational duration of such devices.
Portable Electronic Devices
In handheld instruments, GPS receivers, and pagers.
The LTC3401EMS operates at input voltages as low as 0.5V, enabling full utilisation of battery energy and maintaining stable operation even during low-battery conditions.
Display and Backlight Systems
The LTC3401EMS is suitable for applications such as CCFL backlighting.
Its high switching frequency (up to 3MHz) permits the use of small inductors and capacitors, meeting the demands of slimline designs.
Power Backup Systems
In battery backup applications.
The LTC3401EMS's wide input voltage range and high output current capability ensure smooth transition to the backup power source when the primary power fails.
As a high-performance synchronous boost converter, the LTC3401EMS delivers an ideal power solution for portable electronics through its compact MSOP-10 package, up to 97% efficiency, and mere 38μA quiescent current.
As portable devices become increasingly feature-rich, demands on power management ICs grow correspondingly. The LTC3401EMS stands as an excellent choice to meet these evolving requirements.
