What are the key features of MAX20034ATIS/VY+T?
- Ultra-low 17 µA quiescent current extends battery life in standby-heavy designs
- Wide 3.5 V to 36 V input range supports automotive and industrial voltage rails
- Adjustable switching frequency 200 kHz to 2 MHz enables optimized inductor sizing and EMI trade-offs
- Dual-channel current-mode PWM control with independent output regulation
- Compact 28-LFCSP (5x5x0.75 mm) package minimizes PCB footprint
What is MAX20034ATIS/VY+T used for?
The MAX20034ATIS/VY+T is suited for automotive infotainment and ADAS systems where a wide 3.5 V to 36 V supply rail must power multiple regulated outputs with minimal standby loss. Its 17 µA quiescent current makes it ideal for always-on control modules in hybrid and electric vehicles. Industrial power supplies and smart building controllers also benefit from its dual-channel architecture and programmable 200 kHz to 2 MHz switching frequency.

Frequently Asked Questions
What input voltage range does the MAX20034ATIS/VY+T support, and how does that fit automotive battery rails?
The MAX20034ATIS/VY+T accepts 3.5 V to 36 V input, covering the full 12 V automotive battery range including cold-crank dips and load-dump transients up to 36 V. This wide range lets designers power the device directly from the vehicle bus without a pre-regulator, simplifying the power tree in ADAS and infotainment modules.
How does the 17 µA quiescent current of the MAX20034ATIS/VY+T benefit always-on automotive ECUs?
With only 17 µA quiescent current, the MAX20034ATIS/VY+T draws negligible power when the vehicle is parked and the ECU is in standby, extending battery life over days of idle time. At a 12 V supply this equates to roughly 200 µW of standby dissipation, meeting strict OEM dark-current budgets for keyless-entry and telematics control units.
Which switching frequency range does the MAX20034ATIS/VY+T offer, and what design trade-offs does it enable?
The device supports a programmable switching frequency of 200 kHz to 2 MHz. Lower settings around 200 kHz allow larger, higher-efficiency inductors for heavy-load applications, while 2 MHz operation enables inductors under 1 µH and reduces capacitor size, shrinking overall solution footprint for compact industrial and automotive PCBs.
For a dual-rail industrial power supply needing independent regulation, is the MAX20034ATIS/VY+T a viable choice?
Yes. The MAX20034ATIS/VY+T integrates two independent current-mode PWM buck controllers, each with separate compensation and enable pins, so a single IC can regulate two distinct output voltages simultaneously. The 28-LFCSP package measures 5x5x0.75 mm, fitting dual-rail industrial converters where board space is constrained and an external 3.3 V fixed output option is also available.
