LM2623LD Integrated Circuits (ICs)

The LM2623LD is a high-efficiency, DC-to-DC switching regulator designed to operate at currents up to 2.6 A in both buck and boost configurations. It can be used to supply a wide variety of systems with regulated power, including ‘always-on’ linear regulators that typically draw high currents with poor efficiency. As a switching regulator, this device offers high-efficiency step-down voltage conversion with a single inductor configuration, as well as high-voltage buck or boost regulation with a single inductor or an external inductor for higher voltage regulation.

The LM2623LD is highly efficient and provides excellent transient response, making it suitable for powering a variety of portable and embedded devices, from cell phones to mobile devices. It can also be used as an auxiliary regulator to support higher current-consuming loads.

The LM2623LD offers a wide input voltage range, along with a low dropout (LDO) mode, which allows the system to maintain regulation even when VIN drops below the regulated output voltage. It has an adjustable output voltage range between 0.8 - 5.5V, with a high-side current sense for improved accuracy. The device also includes an optional soft-start feature, limited short circuit protection, and an enable input for system power management.

The LM2623LD uses pulse-width modulation (PWM) as its switching technique. This involves driving an external MOSFET with a fixed on-time, which switches the device at a frequency determined by the value of a single external capacitor. This fixed frequency allows for an optimized design, with minimized size and cost. The LM2623LD also features electrostatic discharge (ESD) protection, with a maximum current rating of ±10 kV.

In summary, the LM2623LD is a high-efficiency, low-dropout switching regulator that is suitable for a wide range of applications. It offers an adjustable output voltage range with an optional soft-start feature, limited short circuit protection, and an enable input for system power management. With its PWM switching technique and ESD protection, it is an excellent choice for powering portable, embedded, and light-load applications.
