- Current-mode PWM control providing inherent cycle-by-cycle current limiting and fast transient response for dynamic loads
- Adjustable output voltage from 0.6 V to 4.5 V covering a wide range of modern low-voltage processor and memory supply rails
- Wide 3 V to 5.5 V input voltage range compatible with USB, single-cell Li-ion, and 3.3 V/5 V bus-powered applications
Applications
The LM2833XMY is designed for portable electronics, USB-powered devices, and point-of-load converters requiring a compact, high-frequency DC-DC switching regulator in a small footprint. Its adjustable 0.6 V to 4.5 V output makes it suitable for generating processor core voltages, DDR memory rails, and low-voltage peripheral supplies from a 5 V or 3.3 V bus. The device is also used in wearable devices, IoT sensor nodes, and embedded systems where efficiency and small solution size are priorities.

Frequently Asked Questions
What is the switching frequency of the LM2833XMY?
The LM2833XMY operates at a fixed 1.5 MHz switching frequency, which allows the use of smaller external passive components (inductors and capacitors) compared to lower-frequency regulators, reducing the overall PCB footprint and solution cost.
What is the input voltage range of the LM2833XMY?
The LM2833XMY accepts an input voltage between 3 V and 5.5 V with a nominal 5 V supply, making it compatible with USB-powered systems, 3.3 V rails, and single-cell Li-ion battery outputs in the 3.0 V to 4.2 V range.
What output voltage range does the LM2833XMY support?
The LM2833XMY supports an adjustable output voltage from 0.6 V to 4.5 V, covering modern processor core voltages, DDR memory supplies, and a wide range of low-voltage logic and analog circuit rails in a single flexible design.
What package does the LM2833XMY come in?
The LM2833XMY is available in a 10-pin MSOP package (JESD-30 code S-PDSO-G10), a compact surface-mount package that enables small PCB layouts suitable for space-constrained portable device and module designs.
What control method does the LM2833XMY use?
The LM2833XMY uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting, improved line and load transient response, and simplified compensation network design compared to voltage-mode control architectures.
