MAX15034AAUI+

The MAX15034AAUI+ is a flexible and highly efficient DC to DC controller IC with an integrated 10-bit DAC. It is designed to accommodate a wide range of applications using either buck, boost, buck-boost, or SEPIC topologies. The MAX15034AAUI+ provides up to 500mA of output current at 5V, making it ideal for powering FPGAs, general processors, motherboard and peripheral chip sets, cellular telephones, and many other applications. Additionally, the MAX15034AAUI+ features low quiescent current and ultra-low dropout operation at output levels above 2.5V, making it an ideal solution for cost-sensitive portable and battery-powered applications.

The MAX15034AAUI+ can be either enabled externally or driven by an internal clock. Enabled from the external pin, the MAX15034AAUI+ will transition to the next step in the power-on-reset procedure. The MAX15034AAUI+ also provides programmable soft-start to prevent inrush currents and system shocks resulting from the sudden power-up of the application. A power-on-reset circuit is integrated in the MAX15034AAUI+, which monitors the voltage on the VDD pin and provides an assertion signal when the output voltage is at a fixed level.

At the heart of the MAX15034AAUI+ is a DC/DC controller with an integrated simple loop compensation, which maintains a stable switching operation with a wide variety of external power supply requirements. The output voltage of the controller is internally trimmed with a 10-bit DAC, providing a wide range of adjustments through the I2C interface. The MAX15034AAUI+ utilizes an optimized PWM control system to provide variable frequency and burst mode control, making it suitable for a variety of applications.

In addition, the MAX15034AAUI+ offers additional features such as overvoltage protection, inrush control, thermal shutdown, power good monitor, and programmable undervoltage lock-out. All these features ensure the protection of the entire system and the operation of the power converter in demanding applications. The MAX15034AAUI+ is an ideal DC-DC controller for applications that require high efficiency and fine tuning of the output voltage.

In conclusion, the MAX15034AAUI+ is a highly efficient and flexible DC-DC controller IC offering variable frequency and burst mode control, integrated PWM control system, integrated 10-bit DAC, low quiescent current operation, programmable soft-start, power-on-reset, overvoltage protection, inrush control, thermal shutdown, power good monitor and programmable undervoltage lock-out. The MAX15034AAUI+ is a great solution for applications that require high efficiency and fine tuning of the output voltage.
