Product details
Overview
MAX20057ATIK/VY+ from Analog Devices is an automotive-grade triple-output power management IC integrating two synchronous buck converters (5V/3.5A and 3.3V/2A) and a 36V asynchronous boost controller with 2.1MHz/400kHz switching options. It operates from 3.5V to 36V input, sustains regulation down to 2V battery during cold-crank, and delivers precise power sequencing for instrument clusters and start-stop systems.
For engineers reviewing the MAX20057ATIK/VY+ datasheet, MAX20057ATIK/VY+ pinout, MAX20057ATIK/VY+ application, or MAX20057ATIK/VY+ equivalent, key selection criteria include its -40°C to +125°C automotive qualification, 28-pin TQFN-EP package, dual-phase 180° out-of-phase buck operation, spread-spectrum EMI reduction, and FSYNC-programmable skip/FPWM/synchronization modes.
Technical Context
The MAX20057ATIK/VY+ implements valley-current-mode control for both buck converters, enabling stable operation across wide input ranges (3.5V–36V) and supporting forced PWM, skip, and external clock synchronization via FSYNC. Its 180° phase shift between Buck1 and Buck2 minimizes input ripple, while the boost controller uses current-mode control with 50mV current-sense threshold and programmable UVLO (4.5V rising, 2.05V falling).
Internal architecture includes independent enable pins (EN1/EN2/EN3), dedicated PGOOD indicators per buck rail, thermal shutdown at 170°C with 20°C hysteresis, and EXTVCC switchover to bypass the internal 5V BIAS LDO-reducing dissipation when powered from external 3.25V–5.5V sources or buck outputs.

Pinout & Package
MAX20057ATIK/VY+ is housed in a thermally enhanced 5mm × 5mm, 28-pin TQFN-EP package with exposed pad (EP) connected to AGND for optimal heat dissipation. The package supports high-power density automotive designs and requires proper separation of PGND and AGND planes per layout guidelines.

| LX1, LX2 | Power switch node connections | Drive external inductors; require low-ESR ceramic bootstrap capacitors (BST1/BST2) for high-side gate drive |
| PGOOD1, PGOOD2 | Open-drain power-good indicators | Assert low if output drops below 93.5% of nominal; high-impedance above 95%; used for rail sequencing and fault signaling |
| FSYNC | External clock synchronization input | Accepts 250kHz–2.6MHz signal; enables PLL lock, 180° phase alignment, or skip/FPWM mode selection |
| EXTVCC | External bias supply input | Accepts 3.25V–5.5V; disables internal 5V LDO to reduce dissipation and improve light-load efficiency |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-output automotive PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4333-AEC1 | Single 3.5A buck + dual 2A bucks; no integrated boost; 2.2MHz fixed frequency only | Lacks cold-crank support below 3.5V; requires external boost for sub-3V operation | Select when boost is implemented externally and board space allows separate boost IC |

FAQ
What is the minimum input voltage supported by MAX20057ATIK/VY+ during cold-crank conditions?
The MAX20057ATIK/VY+ maintains regulation of its buck outputs down to 2.05V battery input when the boost controller is enabled. This is achieved via the integrated 36V asynchronous boost stage, which pre-regulates the input to sustain buck converter operation during automotive cold-crank events. The boost UVLO falling threshold is factory-configured at 2.05V, ensuring continuous functionality even below standard 3.5V minimum input.
Does MAX20057ATIK/VY+ support external synchronization of switching frequency?
Yes, MAX20057ATIK/VY+ supports external synchronization via the FSYNC pin. When driven with a clean clock signal (250kHz–2.6MHz), the device uses an internal PLL to lock its buck and boost switching frequencies to the external source. A 50% duty cycle on FSYNC achieves 180° phase alignment between Buck1 and Buck2, reducing input ripple. Spread spectrum is disabled during external sync, but modulation on the driving clock passes through unaffected.
How does the EXTVCC feature improve efficiency in MAX20057ATIK/VY+ designs?
The EXTVCC pin in MAX20057ATIK/VY+ allows bypassing the internal 5V BIAS LDO by connecting an external 3.25V–5.5V supply-such as a buck output or system rail. This eliminates LDO dropout losses, reduces total IC power dissipation, and scales bias current with duty cycle when fed from a buck output. As a result, light-load efficiency improves significantly, especially in always-on automotive modules where quiescent current directly impacts battery drain.
What protection features are integrated into MAX20057ATIK/VY+?
MAX20057ATIK/VY+ integrates cycle-by-cycle current limiting on all three channels, thermal shutdown at 170°C with 20°C hysteresis, undervoltage lockout on BIAS (3.1V rising / 2.6V falling) and boost input (4.5V rising / 2.05V falling), soft-start for controlled ramp-up, and open-drain PGOOD indicators with 20μs debounce. Each buck channel also includes overvoltage and undervoltage detection tied to its respective PGOOD output.
Can MAX20057ATIK/VY+ be used in non-automotive applications?
While MAX20057ATIK/VY+ is AEC-Q100 Grade 0 qualified and optimized for automotive environments (-40°C to +125°C), its wide 3.5V–36V input range, low quiescent current, and robust protection make it suitable for industrial and transportation applications requiring high-reliability power conversion-such as railway control units, off-road vehicle ECUs, or ruggedized IoT gateways-provided thermal and layout constraints match the automotive-grade validation.
