What are the key features of MAX20034ATIR/VY+?
- Dual switching controller with 3.5 V to 42 V input range and ultra-low 17 µA quiescent current for battery-powered and always-on automotive systems
- Adjustable switching frequency from 200 kHz to 2 MHz enables optimization between efficiency and component size in DC-DC converter designs
- Integrated fixed 3.3 V LDO output alongside dual PWM controllers in a compact 28-pin 5×5 mm TQFN-EP package
What is MAX20034ATIR/VY+ used for?
The MAX20034ATIR/VY+ is designed for automotive and industrial applications requiring dual-output DC-DC conversion from a 12 V to 42 V bus, such as ADAS modules, telematics control units, and factory automation nodes that need always-on low quiescent current operation. Its 200 kHz to 2 MHz frequency flexibility and wide input range also make it suitable for 24 V industrial rail regulators, server auxiliary rails, and multi-rail power sequencing circuits.

Frequently Asked Questions
What input voltage range and switching frequency does the MAX20034ATIR/VY+ support?
The MAX20034ATIR/VY+ accepts input voltages from 3.5 V to 42 V and supports adjustable switching frequencies from 200 kHz to 2 MHz, allowing designers to tune for either minimal inductor size at high frequency or peak efficiency at lower frequencies in dual-output automotive and industrial DC-DC converters.
How does the 17 µA quiescent current of the MAX20034ATIR/VY+ benefit automotive always-on systems?
With only 17 µA quiescent current, the MAX20034ATIR/VY+ is well suited for automotive always-on loads such as keyless entry, telematics wake-up circuits, and body control modules that remain powered from a 12 V battery during vehicle sleep states. This low Iq prevents excessive battery drain over multi-week parking periods, meeting OEM requirements for standby current under 1 mA.
Is the MAX20034ATIR/VY+ a viable solution for replacing discrete dual-supply regulators in a 48 V mild hybrid system?
Yes, the MAX20034ATIR/VY+ supports up to 42 V input, which covers 48 V mild hybrid bus dips below that threshold. It delivers dual programmable outputs via current-mode PWM controllers plus a built-in 3.3 V LDO, replacing 3 discrete regulator ICs in a single 28-pin 5×5 mm TQFN-EP package, reducing BOM count and PCB area in 48 V system power stages.
