MAX1623EAP+

The MAX1623EAP+ is a low dropout (LDO) linear voltage regulator designed to provide a regulated output voltage between 1.23V and 3.5V, with a 3.2A output current. It is ideal for use with single-cell lithium-ion applications, such as portable media players, digital still cameras, and PDAs, enabling online downloads with low battery drain. The device includes an internal soft-start and a low-power shutdown mode for power saving and a power-good output that can be used to indicate when the supply voltage has been regulated to the desired level.

The MAX1623EAP+ was designed for applications requiring very low output ripple, high power efficiency, and low oscillator noise. The device operates with a fixed-frequency PWM control scheme, making it ideal for applications where low noise is a priority. Additionally, the device operates from an input voltage range of 9V to 16.5V, providing an ideal solution for applications that operate in both mobile and non-mobile environments.

The MAX1623EAP+ is entirely self-contained, with integrated MOSFETs and synchronous rectification. This allows the device to provide a 3.2A output current without the need for external components. The device also features over temperature and over-current protection to ensure its efficient operation. It incorporates a user-selectable soft-start to minimize in-rush current, as well as an adjustable current limit to provide protection against load surges.

The MAX1623EAP+ operates from an input voltage range of 9V to 16.5V and provides up to 3.2A of output current. Its highly efficient fixed-frequency PWM control scheme results in very low output ripple due to its integrated low-dropout (LDO) linear voltage regulator. The device also includes various protection features, including over-temperature and over-current protection, as well as user-selectable soft-start and adjustable current limit. The MAX1623EAP+ is ideal for single-cell lithium-ion applications, such as portable media players, digital still cameras, and PDAs, enabling online downloads with low battery drain.
