The MAX17290ETCC+ is a space-saving, dc-dc bus converter ideal for use in battery-powered applications, providing up to 2.3A of load current at 4.5Vout. It features a low quiescent current (2μA), which helps to extend battery life. The MAX17290ETCC+ is an adjustable frequency, current-mode synchronous buck regulator with internal MOSFET switching transistors that support on/off logic level control. It also has a programmable soft-start/hiccup protection feature to slow down the turn-on of the load, helping to reduce inrush current.

The MAX17290ETCC+ uses pulse-width modulation (PWM) to control the voltage output. The regulator senses the output voltage and regulates the on/off duty cycle of the PWM signal to ensure a stable output voltage. It provides 2-9V of adjustable output voltage, making it ideal for various applications like motor drives, storage systems, and battery-powered equipment. The MAX17290ETCC+ also features ultra-wide input voltage range from 2.3V to 18V, making it suitable for use in different applications.

The MAX17290ETCC+ has an adjustable switching frequency (270kHz to 2.2MHz). The switching frequency range has been optimized to balance the efficiency while providing a wide range of output voltage. The step-size voltage adjustment of 0.1V allows the user to set the output voltage, depending on the application\'s requirements.

The MAX17290ETCC+ is designed to maximize electrical efficiency. It has a sleep mode that reduces the operating current to 10μA, allowing the device to remain off while consuming minimal power. The regulator also has current-limiting circuitry and thermal overload protection to further protect the device from damage due to excessive input or output currents.

The MAX17290ETCC+ is ideal for low input and output voltage applications, as it can generate 4.5V from supplies as low as 2.3V and can drop 3.3V as low as 0.8V. It also supports logic level control, providing an on/off control for the output voltage. The regulator also includes a programmable soft-start/hiccup protection feature, which helps to slow down the turn-on of the load and reduces the inrush current.

Overall, the MAX17290ETCC+ is a versatile, current-mode synchronous buck regulator that features adjustable frequency control, current-limiting, and thermal protection. It supports a wide range of output voltage and can reduce power consumption in sleep mode. Its ultra-wide input voltage range allows it to be used in applications with a variety of input voltages, making it ideal for low input and output voltage applications.
