The LM2733YMFX/NOPB is a DC-DC switching regulator with a wide voltage range and system flexibility. LM2733YMFX/NOPB provides a broad selection of switching regulators for different output voltage levels. These regulators are ideal for PC, notebooks, and other applications. It is well suited to a variety of applications such as CPU power, display power, gaming consoles, and data centers.

The main features of the LM2733YMFX/NOPB are wide operating voltage (4.5V to 26V), low quiescent current (minimum 2uA), low noise (1uA), low EMI, programmable output voltage (0.6V to 5.05V), low ESR, feedback voltage, over voltage protection (OVP), over current protection (OCP), and over temperature protection (OTP). The device is available in eight package variants ranging from a few square millimeters to nearly half a square inch.

The LM2733YMFX/NOPB is a low power, synchronous, buck regulator ideal for many DC-DC applications. It provides regulated output voltages regulated down from 4.5V to 26V. The switching frequency can be adjusted to a maximum of 2MHz. Programmable feedback voltage allows adjustment of the reference voltage to a range of 0.6V to 5.05V. This allows operation up to 26V and down to 0.6V, giving it the added capability of LDOs with the efficiency of a DC-DC switching regulator.

The LM2733YMFX/NOPB includes many protection features such as Over Voltage Protection (OVP), Over Current Protection (OCP), and Over Temperature Protection (OTP). OVP prevents the device from going into output overload and over current conditions even with a wide input voltage range. OCP is useful for current sharing in multiple output applications and OTP safely shuts down the device in case of thermal overload.

The LM2733YMFX/NOPB operates in either PFM (pulse frequency modulation) or PWM (pulse width modulation) mode, depending on the load current. In PFM mode, the device switches off at light load to reduce power consumption while in PWM mode, the device maintains full control over the output voltage to ensure a reliable and stable power supply.

The LM2733YMFX/NOPB provides efficient power conversion with a wide operating voltage range and an impressive list of features, making it ideal for many power applications. With its robust protection and low quiescent current, it is ideal for small, energy-efficient power designs.
