What are the key features of LTC3542EDC#TRMPBF?
- Synchronous current-mode buck converter with burst-mode control achieves high efficiency at light loads from a 2.5 V to 5.5 V input rail
- 0.5 A output current with 0.6 V to 5.5 V adjustable output voltage covers a wide range of portable and automotive supply rails
- Automotive-grade 6-pin DFN (2x2 mm) package minimizes PCB footprint for space-constrained battery-powered and vehicle ECU designs
What is LTC3542EDC#TRMPBF used for?
The LTC3542EDC#TRMPBF is designed for automotive accessory modules, portable industrial sensors, and battery-powered IoT devices requiring an efficient step-down regulator from a single-cell Li-Ion or multi-cell alkaline stack. Its burst-mode operation at light loads extends battery life in duty-cycled systems such as wireless sensor nodes and wearable devices. The 2.5 V minimum input allows operation from nearly fully discharged single-cell Li-Ion batteries, maximizing energy utilization.

Frequently Asked Questions
What input voltage range does LTC3542EDC#TRMPBF accept and how does that fit single-cell Li-Ion applications?
The LTC3542EDC#TRMPBF accepts inputs from 2.5 V to 5.5 V, with a nominal of 3.6 V. This range precisely matches a single-cell Li-Ion battery from nearly fully discharged at 2.5 V through fully charged at 4.2 V, enabling efficient step-down conversion across the entire battery discharge curve.
How does burst-mode control reduce power consumption in LTC3542EDC#TRMPBF during light loads?
In burst mode the converter enters a low-power sleep state between switching pulses when output current is low, reducing quiescent current to microamp levels. This dramatically extends battery life in duty-cycled IoT nodes and wearables where the load switches between 0.5 A active and near-zero sleep states many times per second.
What output voltage range is achievable with LTC3542EDC#TRMPBF and how is it set?
The output voltage is adjustable from 0.6 V to 5.5 V using an external resistor divider. This flexibility allows a single device to power MCU cores at 1.2 V, digital logic at 1.8 V or 3.3 V, and RF modules at 5 V, covering most portable and automotive sub-system supply requirements.
What automotive or industrial certifications apply to LTC3542EDC#TRMPBF and what package does it use?
LTC3542EDC#TRMPBF is an automotive-qualified device in a 6-pin DFN package measuring approximately 2x2 mm. The small form factor and automotive-grade temperature and reliability specifications make it suitable for vehicle ECU sub-regulators, in-cabin sensor modules, and industrial edge devices operating across a -40°C to +125°C temperature range.
