LMZ22005TZE/NOPB

DC-DC converters are an electronic device that converts an input voltage to a different output voltage through a switching frequency. The LMZ25005TZE/NOPB is a two-stage DC-DC converter that delivers an industry-leading efficiency of up to 95%. The device is popular because of its high efficiency, small form factor, and wide input voltage range of 0.6V to 5.5V. With an output current of up to 15 Amps and a fast transient response, this device can be used in space-constrained systems that require higher currents and low-power operation.

The LMZ25005TZE/NOPB is a synchronous step-down DC/DC converter that combines a peak-switching constant-regulator control loop with an external capacitor and a synchronous rectifier based on N-channel power MOSFETs for the output stage. It operates from an input voltage supply of 0.6V to 5.5V and a maximum output voltage of 0.5V to 2.5V. This device is suitable for applications such as DSCs (Digital Stereo Cameras), communications systems, and industrial control systems.

The LMZ25005TZE/NOPB is available in a thermally-efficient and space-saving 6-lead small-outline package (SOP) and is rated for operation over a temperature range of -40 to +85 degrees Celsius. This device features built-in overvoltage and short-circuit protection and has an adjustable switching frequency of up to 2MHz, an adjustable soft-start, and the capability to support a wide voltage range.

The LMZ25005TZE/NOPB’s working principle relies on a special synchronous buck control circuit, in which the power MOSFET is driven in both directions to increase efficiency. The circuit has a constant-regulator feedback loop and a synchronous rectifier based on N-channel power MOSFETs for the output stage. The device uses a combination of peak-switching and linear-regulator control to achieve optimal efficiency. The integrated loop compensation eliminates external loop-compensator components such as external resistors and capacitors.

The LMZ25005TZE/NOPB is an ideal solution in applications where space is limited but high-efficiency and high-currents are required. It provides a low-profile, thermally-efficient SOP package and an adjustable switching frequency up to 2MHz and adjustable soft-start. With an integrated loop compensation that eliminates the need for external loop-compensator components, the LMZ25005TZE/NOPB prevents external circuit complications and simplifies implementation of the design. Without needing to eat up board space for external components this device reduces the time needed to design and implements a DC-DC converter. This synchronous buck converter is an easy and inexpensive solution that can be used in applications such as digital stereo cameras, communications systems, and industrial control systems.
