The MAX17292EUBA+ is a synchronous buck voltage regulator for DC-DC applications with applications including automotive, point of load industrial systems, telecom, computing, and server. It is a multi-output buck regulator for systems with multiple load voltages including 2.5V, 1.8V, 1.2V and a configurable PGOOD output. This voltage regulator is designed with advanced Capacitor-Free operation and a wide operating temperature range. It has an operating temperature range of -40 to +150°C, an input voltage range of 4.5V to 28V with a maximum output voltage of 2.6V, and a maximum efficiency of 95%, making it ideal for automotive and industrial applications.

The MAX17292EUBA+ incorporates a unique power switch design that eliminates large external capacitors and prevents dropout of the output voltages. This ensures fast switching and helps extend the life of the regulator. Other features include integrated 40V MOSFETs, tracking capability, adjustable soft-start time, precision output voltage regulation, and programmable frequency. Programmable features include enable pin, power good, soft start, and enable over-temperature protection.

The MAX17292EUBA+ is designed for robust system reliability and compliance, providing EMI certified under CISPR22/EN55022 Class B and low RFI/EMI performance. It is also RoHS and REACH compliant, enabling its use in high-efficiency, high-reliability applications. The device is designed to meet automotive load-dump & HBM/CDM noise, enabling it for use in automotive applications.

The MAX17292EUBA+ operates through a synchronous switching principle, which utilizes the primary switch that controls the output voltage between the input and output. The primary switch is driven by an internal oscillator, which is in turn driven by an enable signal. This enables the regulator to provide a consistent output voltage with a minimal voltage drop across the primary switch. The output voltage is regulated by the internal error amplifier, which can be programmed to fine-tune the output voltage accuracy. In addition, the regulator also features a tracking capability, which allows it to track up to three other regulators on the same board.

The MAX17292EUBA+ also includes integrated over-temperature protection, over-current protection and short-circuit protection. The device also incorporates an adjustable soft-start time, which eliminates harmful inrush currents that can occur when the regulator is enabled. The soft-start time is adjustable, allowing the output to be ramped up slowly to avoid any spikes or surges in the input voltage.

The MAX17292EUBA+ is a powerful and versatile voltage regulator that can be utilized in a wide range of applications. Its wide operating temperature range and efficient power management make it an ideal choice for automotive, industrial, and point of load applications. Its capacitor-free operation simplifies the design process, reducing development time and cost. The integrated features and protections enable the device to operate safely and reliably for numerous applications.
