What are the key features of LM2833XSD/NOPB?
- 3.0 A continuous output current with 1.5 MHz or 3 MHz selectable switching frequency for compact filter design
- Current-mode PWM control enables fast transient response and inherent cycle-by-cycle current limiting
- Adjustable output voltage from 0.6 V to 4.5 V suits a wide range of point-of-load DC-DC applications
- 3 V to 5.5 V wide input voltage range compatible with single-cell Li-ion and regulated 5 V rails
What is LM2833XSD/NOPB used for?
The LM2833XSD/NOPB is well suited for portable consumer electronics, DSP and FPGA core power rails, and battery-powered IoT devices that demand high-efficiency step-down conversion in a compact footprint. Its 3.0 A current capability and adjustable output make it a practical choice for powering microcontrollers, FPGAs, and communication modules from a 3.3 V or 5 V system bus. The high switching frequency minimises external inductor and capacitor size, saving PCB area in space-constrained designs.

Frequently Asked Questions
What is the maximum continuous output current the LM2833XSD/NOPB can supply?
The LM2833XSD/NOPB supports a maximum continuous output current of 3.0 A, making it suitable for powering processor cores, FPGAs, and multi-channel sensor loads from a single compact step-down regulator. The current-mode control architecture also provides cycle-by-cycle overcurrent protection at this 3.0 A rating.
How does the switching frequency selection affect inductor size in an LM2833XSD/NOPB design?
Selecting the 3 MHz switching frequency instead of 1.5 MHz reduces the required inductance by roughly half, allowing inductors as small as 1 µH in a 1.0 mm × 0.6 mm package. This directly shrinks total solution footprint by 30–40 % compared with a 1.5 MHz design, benefiting space-constrained PCB layouts in wearables and portable devices.
Which input voltage rails are compatible with the LM2833XSD/NOPB?
The device accepts input voltages from 3 V to 5.5 V, making it compatible with single-cell Li-ion batteries near end-of-discharge (3 V), regulated 3.3 V rails, and standard 5 V system buses. The 5.5 V absolute maximum input ensures safe operation even with minor load-transient overshoots on the 5 V rail.
In which scenarios is the LM2833XSD/NOPB a preferred alternative to a linear regulator for 3.3 V to 1.8 V conversion?
When the load current exceeds 500 mA, a linear LDO drops (3.3 V − 1.8 V) × 1 A = 1.5 W as heat, requiring a heatsink or large copper pour. The LM2833XSD/NOPB delivers 1.8 V at 3.0 A with typical efficiency above 85 %, dissipating less than 270 mW in a thermally friendly 10-pin no-lead package and eliminating external thermal management hardware.
