The MAX20015–MAX20018 family of ASIL B-compliant high-efficiency switching regulators delivers up to 3A load current from 0.5V to 3.8V. The devices operate from a 2.7V to 5.5V input voltage range, making them ideal for on-board point-of-load and post-regulation applications. Total output error is less than ±1.5% over load, line, and temperature.

The devices feature fixed-frequency PWM mode operation, with a 2.2MHz switching frequency. High-frequency operation allows for an all-ceramic capacitor design and small external components.

The low-resistance on-chip switches ensure high efficiency at heavy loads while minimizing critical inductances, making the layout a much simpler task with respect to discrete solutions. Following a simple layout and footprint ensures first-pass success in new designs.

The devices provide an enable input, spread-spectrum enable input, and RESET output. The output voltage can be preset at the factory to allow customers to achieve ±1.5% output-voltage accuracy without using expensive 0.1% resistors. In addition, the output voltage can be set to any customer value by using two external resistors at the feedback, with 0.5V internal reference. The devices offer factory-programmable soft-start and RESET hold times.

The 10-pin TDFN exposed pad devices include overtemperature shutdown and overcurrent limiting. All devices are designed to operate over the -40°C to +125°C ambient temperature range.

Product Detail

The MAX20074 evaluation kit (EV kit) demonstrates the performance and behavior of the MAX20074, a part in the MAX20015–MAX20018/MAX20073/MAX20074 family of pin-compatible, low-voltage, step-down switching regulator ICs.

The regulator delivers current up to 3A at an output voltage between 0.5V and 3.8V. The device operates from a 2.7V to 5.5V input supply voltage, making it ideal for post-regulation and point-of-load applications. The total error over load, line, and temperature ranges is 1.5%. The base switching frequency is 2.2MHz, which allows for all-ceramic capacitor application designs. The regulator can either be synchronized to an external clock or placed in a power-saving skip mode for increased efficiency at light loads.

The regulator provides an enable input and fault flag output. The output voltage can be set using an external resistor-divider and an internal 0.5V reference. Alternatively, it can be programmed at the factory for a specific output voltage, achieving 1.5% output accuracy without resorting to expensive 0.1% resistors. The soft-start time and fault hold time can also be factory programmed.

The regulators include overtemperature shutdown and overcurrent limiting. They are designed to continuously operate over the -40°C to +125°C ambient temperature range.
