Key Features
- Dual independent 2.2MHz current-mode PWM step-down controllers enable two separate regulated output rails from a single IC, reducing BOM count in multi-rail power systems
- Wide 3.7V to 28V input range with 28V absolute maximum supports 12V and 24V automotive, industrial, and telecom bus voltages in a single design
- Compact 20-pin 5x5mm LFCSP package with exposed pad provides efficient thermal dissipation for high-power density automotive and industrial converter designs
Applications
The MAX16922ATPO/V+T is designed for automotive body electronics, ADAS, and infotainment systems where dual step-down regulation from a 12V or 24V vehicle bus is required with high switching frequency to minimize inductor and capacitor size. Its wide input range and current-mode control also suit industrial PLCs, motor drives, and 24V distributed power architectures needing tightly regulated dual output rails. The 2.2MHz switching frequency allows use of small ceramic capacitors and thin inductors for compact PCB layouts in space-constrained applications.

Frequently Asked Questions
What switching frequency does the MAX16922ATPO/V+T operate at, and how does this affect passive component sizing?
The MAX16922ATPO/V+T switches at 2.2MHz, which allows designers to use inductors as small as 1µH to 4.7µH and ceramic capacitors in the nanofarad to low-microfarad range. This high switching frequency significantly reduces the PCB footprint of the power stage compared to lower-frequency solutions operating at 200kHz to 600kHz.
What is the input voltage range of the MAX16922ATPO/V+T, and for which bus voltages is it rated?
The MAX16922ATPO/V+T accepts an input voltage from 3.7V to 28V in normal operation, with a 28V absolute maximum rating. This covers standard automotive 12V and 24V bus voltages as well as industrial 24V rails, making it versatile for both passenger vehicle and commercial vehicle power systems.
How does current-mode PWM control in the MAX16922ATPO/V+T improve transient response compared to voltage-mode control?
Current-mode PWM control in the MAX16922ATPO/V+T directly senses the inductor current each switching cycle, providing inherent cycle-by-cycle current limiting and faster load transient response than voltage-mode control. This allows the regulator to respond to load steps within 1µs to 5µs, maintaining output voltage regulation within tight bounds for sensitive digital loads.
How many independent output rails can the MAX16922ATPO/V+T regulate simultaneously?
The MAX16922ATPO/V+T integrates 2 independent step-down controller channels in a single 20-pin LFCSP package. Each channel can be programmed independently for output voltage and current limit, enabling a complete dual-rail power supply solution with two regulated outputs from a shared 12V or 24V input bus.
