The MAX1762EUB+ is a step down DC / DC switching controller specifically designed for efficient industrial and automotive applications with wide input voltage range and minimal external component count. This device can be used in a variety of applications, including systems that require energy conservation, automotive environments and devices with harsh environmental conditions. The MAX1762EUB+ has a wide input voltage range of 2.75V to 42V, enabling it to meet the needs of many applications, including automotive applications.

The MAX1762EUB+ utilizes an adjustable pulse frequency control (PFC) to achieve high efficiency, which eliminates the need for an external gate driver or isolation in the system. It provides a programmable low-ripple current mode control with continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) operation, as well as soft start for optimal start up. The device incorporates a current sensing element to reduce the current sense voltage spread of the power MOSFETs, thus reducing the voltage spread of the switching frequency to protect the system from audible noise and ensure good EMI performance. The device also offers 350mV reference voltage for light load applications.

The MAX1762EUB+ provides adjustable ripple current protection, over-voltage protection, and over-current protection, making it extremely reliable in harsh environments. It also offers short circuit protection and auto-restart feature after the short-circuit condition is removed. In addition, it includes a power-OK pin to indicate the regulated voltage level, allowing the system to examine the output voltage before using it. The device has an adequate internal power dissipation capacity and is available in a 6-pin SOT23 package.

The MAX1762EUB+ is ideal for high efficiency, low output ripple, and minimal component count power supply design and a wide array of applications in industrial and automotive systems. It can be used in a variety of DC/DC converter designs such as Buck, Buck-Boost, Flyback, and Boost converters. This device is capable of operating at a wide input voltage from 2.75V to 42V and a wide power range from 1W to 34W, making it a great choice for applications that require an efficient, low component count and robust voltage regulation.
