Product details
Overview
MAX20057ATID/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, operating from 3.5V–36V input with cold-crank support down to 2V. It delivers regulated outputs for instrument clusters and start-stop systems using 180° out-of-phase switching at fixed 400kHz or 2.1MHz frequencies.
For engineers reviewing the MAX20057ATID/VY+ datasheet, MAX20057ATID/VY+ pinout, MAX20057ATID/VY+ application, or MAX20057ATID/VY+ equivalent, key selection considerations include its thermally enhanced 5mm × 5mm TQFN-EP package, 10μA/8μA quiescent current with individual buck rails enabled, spread-spectrum EMI reduction, and FSYNC-programmable operation modes (forced PWM, skip, PLL-sync).
Technical Context
The MAX20057ATID/VY+ implements valley-current-mode control for both buck converters, enabling stable regulation across wide input ranges including automotive cold-crank (down to 2V battery). Its 180° phase shift between Buck1 and Buck2 minimizes input ripple, while the boost controller supports preboost during low-VIN conditions to maintain buck regulation.
FSYNC enables three operational modes: forced fixed-frequency PWM (for transient response), skip mode (ultra-low IQ), and PLL-synchronized operation with external clock. Spread-spectrum modulation (±6% at 2.1MHz) reduces EMI without compromising input voltage range or output stability.
Key Specifications

| Buck1 Output | Fixed 5V ±1% at 3.5A; adjustable 1V–14V with 1V feedback reference |
| Buck2 Output | Fixed 3.3V ±1% at 2A; adjustable 1V–14V with 1V feedback reference |
| Boost Output | Fixed 10V ±0.25V or adjustable; 36V max input, 50mV current-limit threshold |
| Switching Frequency | Factory-set 400kHz or 2.1MHz; ±6% spread-spectrum option available |
| Quiescent Current | 10μA (5V buck on), 8μA (3.3V buck on), 30μA (all regulators on) |
| Thermal Protection | Thermal shutdown at 170°C with 20°C hysteresis; junction-to-ambient θJA = 27°C/W |
Pinout & Package
Package: 28-pin TQFN-EP (5mm × 5mm, exposed pad), RoHS-compliant, thermal resistance θJC = 3°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1, EN2, EN3 | Independent enable inputs | High-voltage tolerant digital enables for Buck1, Buck2, and Boost; allow precise power sequencing |
| FB1, FB2, FB3 | Feedback inputs | 1V reference points for output regulation; support fixed or resistor-divider-adjusted voltages |
| LX1, LX2 | Buck switch node connections | Drive external inductors; require ceramic bootstrap capacitors (BST1/BST2) for high-side gate drive |
| PGOOD1, PGOOD2 | Open-drain power-good indicators | Assert low when output drops below 93.5% of nominal; used for rail enable sequencing and fault signaling |
| FSYNC | External clock synchronization input | Enables PLL lock to external clock; determines phase relationship (e.g., 50% duty cycle → 180° buck phase shift) |
| DL | Boost low-side N-MOSFET gate driver | Sources/sinks up to 1.67A peak; compatible with logic-level MOSFETs when powered by BIAS LDO |
| BIAS, EXTVCC | Internal LDO output / switchover input | 5V internal bias rail; EXTVCC bypasses LDO to reduce dissipation and improve light-load efficiency |
| AGND, PGND1–PGND3 | Analog and power ground terminals | Separate AGND (quiet reference) and dedicated PGNDs per converter minimize noise coupling |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20090ATP/VY+ | Single 5V/3A buck + integrated 36V boost; no second buck channel or 3.3V rail | Suitable for simpler systems needing only one regulated output plus boost | Select when dual-buck integration is unnecessary and board space is constrained |
| TPS65381A-Q1 | Three buck converters (3A/2A/1.5A); no integrated boost; requires external preboost for cold-crank | Requires external boost circuit for sub-6V operation; higher external component count | Select when strict AEC-Q100 Grade 0 qualification is required and boost can be implemented externally |
Compared with MAX20057ATID/VY+, MAX20090ATP/VY+ reduces integration but saves area for single-rail designs, while TPS65381A-Q1 offers higher buck current ratings but lacks on-chip boost-requiring additional components to meet cold-crank specs.

FAQ
What is the cold-crank capability of the MAX20057ATID/VY+?
The MAX20057ATID/VY+ maintains regulated 5V and 3.3V outputs during automotive cold-crank events down to 2V battery input, enabled by its integrated 36V asynchronous boost controller. The boost pre-regulates the buck inputs, allowing continuous operation even when VSUP drops below the buck output voltages. This is confirmed in the Absolute Maximum Ratings and Electrical Characteristics sections, where the "With preboost after initial start-up condition is satisfied" row specifies 2.05V minimum input.
Does the MAX20057ATID/VY+ support external frequency synchronization?
Yes, the MAX20057ATID/VY+ supports external frequency synchronization via the FSYNC pin. When driven with a clean clock signal, its internal PLL locks to the external frequency with 1:1 ratio. The FSYNC input accepts 1.8–2.6MHz signals for 2.1MHz operation or 250–550kHz for 400kHz operation, and the duty cycle controls phase alignment-e.g., 50% duty cycle yields 180° phase shift between Buck1 and Buck2.
What are the thermal characteristics of the MAX20057ATID/VY+ package?
The MAX20057ATID/VY+ uses a 28-pin TQFN-EP package (5mm × 5mm) with an exposed pad thermally connected to the die substrate. Its junction-to-case thermal resistance (θJC) is 3°C/W, and junction-to-ambient (θJA) is 27°C/W on a four-layer board. Thermal shutdown activates at 170°C with 20°C hysteresis, ensuring safe operation under sustained load in automotive under-hood environments.
Can the MAX20057ATID/VY+ operate with only one buck converter enabled?
Yes, the MAX20057ATID/VY+ supports independent enable/disable of each regulator via EN1 (Buck1), EN2 (Buck2), and EN3 (Boost). With only Buck1 enabled, quiescent current is 10μA; with only Buck2 enabled, it is 8μA; and with all three enabled, it is 30μA. This enables flexible power sequencing and dynamic rail management in multi-mode automotive systems.
Is spread-spectrum modulation enabled by default on the MAX20057ATID/VY+?
No, spread-spectrum modulation is a factory-configurable option on the MAX20057ATID/VY+ and is not enabled by default. When activated, it modulates the switching frequency by ±6% around the nominal value (e.g., 2.1MHz) with a triangular waveform period of 110μs. The feature is disabled automatically during external FSYNC synchronization but passes any modulation present on the external clock source.
