Frequently Asked Questions
What input voltage range and maximum output current does LM2833ZMYX/NOPB support?
LM2833ZMYX/NOPB accepts input voltages from 3 V to 5.5 V and can supply up to 3 A of output current. This covers 3.3 V and 5 V supply rails typical in USB-powered equipment and embedded single-board computers.
How low can the output voltage be set on LM2833ZMYX/NOPB and why is that useful?
Output voltage is adjustable down to 0.6 V through an external resistor divider, enabling precise supply for modern sub-1 V processor cores, FPGA core rails, and DDR memory termination voltages without additional linear post-regulators.
What control architecture does LM2833ZMYX/NOPB use and how does it affect transient performance?
LM2833ZMYX/NOPB uses current-mode PWM control, which inherently compensates for input voltage changes each switching cycle. This improves line transient response compared to voltage-mode regulators, reducing output voltage undershoot when load current steps from 0 A to 3 A.
Which compact package does LM2833ZMYX/NOPB come in for high-density power supply layouts?
LM2833ZMYX/NOPB is housed in a 10-pin MSOP with exposed thermal pad, measuring 3.00 mm width. The exposed pad improves heat spreading, allowing full 3 A operation without a heatsink when routed to a copper pour on a standard 2-layer PCB.
