What are the key features of LTC3533EDE#TRPBF?
- 2 A synchronous buck-boost converter with 1.8 V to 5.5 V input range seamlessly regulates output across buck, boost, and transitional modes without discontinuity
- Voltage-mode PWM control with internal compensation simplifies loop design and enables stable operation from a single Li-Ion cell discharging from 4.2 V to 2.7 V
- Small DFN package minimizes PCB footprint for battery-powered portable devices requiring efficient power regulation with minimal board area
What is LTC3533EDE#TRPBF used for?
LTC3533EDE#TRPBF is designed for single-cell Li-Ion or LiPo battery-powered devices that require a regulated output voltage throughout the full battery discharge cycle, from 4.2 V down to 2.7 V. Its buck-boost architecture is particularly valuable in GPS modules, portable medical instruments, and wireless sensor nodes where the battery voltage crosses the regulated output level during operation. The 2 A output current capability supports moderate processing loads and RF transceivers within a compact power supply solution.

Frequently Asked Questions
What input voltage range does LTC3533EDE#TRPBF support, and why does buck-boost matter for Li-Ion applications?
LTC3533EDE#TRPBF accepts input voltages from 1.8 V to 5.5 V, covering the full discharge range of a single Li-Ion cell from 4.2 V charged to 2.7 V depleted. The buck-boost topology maintains a stable output voltage even when the input crosses the output level, which a pure buck or boost converter cannot do without switching architectures.
How much output current can LTC3533EDE#TRPBF deliver, and what loads does this support?
LTC3533EDE#TRPBF delivers up to 2 A of output current, sufficient to power microcontrollers drawing 200–500 mA, RF transceivers requiring 1–1.5 A peak, or sensor arrays totaling under 2 A in portable IoT and medical device designs operating from a single-cell battery supply.
What control method does LTC3533EDE#TRPBF use, and how does it simplify power supply design?
LTC3533EDE#TRPBF uses voltage-mode PWM control with internal loop compensation, eliminating the need for external compensation networks in most designs. This simplifies the PCB design, reduces component count, and ensures stable closed-loop operation across the full 1.8 V to 5.5 V input range with fixed-frequency switching.
When would LTC3533EDE#TRPBF be preferred over a simple boost converter in a battery-powered design?
LTC3533EDE#TRPBF is preferred over a simple boost converter when the regulated output voltage (for example 3.3 V) is close to the battery nominal voltage (3.7 V), so the input sweeps from above 3.3 V when fully charged to below 3.3 V when depleted. A boost-only converter would fail to regulate during the buck portion of the discharge, while LTC3533EDE#TRPBF operates continuously across the full 2 A load range.
