Product details
Overview
MAX16907RATE/V+ from Maxim Integrated is a 3A, current-mode, automotive-grade step-down DC-DC converter with integrated 70mΩ high-side MOSFET, operating from 3.5V to 36V input and delivering 5V fixed or 1V–10V adjustable output. It features 30µA standby current, 2.2MHz switching frequency (adjustable 1–2.2MHz), and operates across –40°C to +125°C for engine control units and ADAS power rails.
For engineers reviewing the MAX16907RATE/V+ datasheet, MAX16907RATE/V+ pinout, MAX16907RATE/V+ application, or MAX16907RATE/V+ equivalent, this page delivers verified electrical specs, thermal behavior under load-dump transients, PGOOD sequencing support, and validated TQFN-16 package layout guidance - all critical for automotive power-supply design validation.
Technical Context
The MAX16907RATE/V+ implements constant-frequency current-mode control with 80ns minimum on-time and 98% maximum duty cycle during cold-crank undervoltage events. Its dual supply inputs (SUP and SUPSW) enable independent biasing of control logic and power switch, supporting robust operation down to 3.5V input while tolerating 42V transients.
It integrates a 5V/100mA BIAS LDO, programmable oscillator with external resistor (RFOSC), synchronization input (FSYNC), and fast-load-transient compensation via transconductance error amplifier (gm = 900µS). Protection includes overvoltage lockout at 110% VFB, thermal shutdown at +175°C with 15°C hysteresis, and automatic-recovery overcurrent limiting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.5V to 36V - supports full automotive battery range including cold-crank (≥3.5V) and load-dump (≤42V transient) |
| Output Current | 3A continuous - sustains full load at +125°C ambient with TQFN-5×5mm exposed pad thermal path |
| Switching Frequency | 2.2MHz (typ, RFOSC = 12kΩ) - enables compact 2.2µH inductor and low-profile ceramic output capacitors |
| Quiescent Current | 30µA (standby, no load, VOUT = 5V) - extends battery life in always-on vehicle modules |
| Feedback Reference | 1.00V (±1.5% over –40°C to +125°C) - ensures stable 5V output regulation across temperature and line/load variation |
| Power-Good Threshold | Rising: 95% VFB, Falling: 92.5% VFB - provides precise sequencing margin for downstream processors |
| Thermal Shutdown | +175°C (typ), 15°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking |
Pinout & Package
MAX16907RATE/V+ is housed in a 16-pin TQFN package (5mm × 5mm, 0.5mm pitch) with exposed thermal pad (EP) requiring connection to a solid ground plane for thermal management and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (FSYNC) | External clock sync input | Accepts 10% higher-frequency external clock; disables internal spread-spectrum when active |
| 2 (FOSC) | Frequency-setting resistor node | Connects to GND via 12kΩ for 2.2MHz operation; sets fSW from 1–2.2MHz |
| 3 (PGOOD) | Open-drain power-good monitor | Asserts low when VOUT drops below 92.5% VFB; used for MCU reset sequencing |
| 4 (OUT) | Switch-node output | Delivers regulated 5V/3A; powers internal circuitry when VOUT = 3–5.5V in standby mode |
| 5 (FB) | Feedback voltage sense | Shorted to BIAS for 5V fixed output; connected to resistive divider for 1–10V adjustment |
| 6 (COMP) | Error amplifier output | Requires RC network to GND for loop stability; gm = 900µS enables fast transient recovery |
| 7 (BIAS) | Integrated 5V LDO output | Supplies internal logic; bypassed with 1µF ceramic capacitor to GND |
| 8 (GND) | Analog/digital ground reference | Primary return path; must be tied to EP and system ground plane |
| 9 (BST) | Bootstrap capacitor node | Requires 0.1µF capacitor between BST and LX to drive high-side MOSFET gate |
| 10 (SUP) | Main supply input | Powers internal LDO; requires ≥4.7µF ceramic decoupling to GND |
| 11–12 (LX) | Switching node | Connects to inductor and Schottky freewheel diode cathode; handles 4A RMS current |
| 13–14 (SUPSW) | High-side switch supply | Powers internal MOSFET driver; requires 0.1µF + 4.7µF ceramic decoupling |
| 15 (EN) | Enable input | Logic-compatible with 3.3V/5V/KL30; 2V threshold with 0.2V hysteresis; 1µA input leakage |
| 16 (I.C.) | Internally connected | Must be tied to GND; not functional as signal pin |
| EP | Exposed thermal pad | Not electrically isolated; mandatory connection to large copper ground plane for thermal dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM61480-Q1 | 4.5V–36V input, 5A output, 2.1MHz fixed frequency, no BIAS LDO, requires external bootstrap capacitor | Lacks integrated 5V BIAS regulator; needs external LDO for biasing, increasing component count | Choose when higher output current (5A) is required and board space allows separate bias supply |
| TPS62933-Q1 | 3V–36V input, 3A output, 2.2MHz fixed frequency, 15µA IQ, no FSYNC or spread-spectrum | No synchronization input or spread-spectrum option; lower quiescent current but less EMI flexibility | Prefer when ultra-low IQ is critical and EMI mitigation relies solely on filtering, not frequency modulation |
Compared with LM61480-Q1 and TPS62933-Q1, the MAX16907RATE/V+ uniquely integrates a 5V BIAS LDO, FSYNC input, and factory-enabled spread-spectrum - making it optimal for space-constrained, EMI-sensitive automotive systems requiring single-chip simplicity and cold-crank resilience.

FAQ
What is the maximum input voltage transient the MAX16907RATE/V+ can withstand?
The MAX16907RATE/V+ is rated for 42V input transients per ISO 7637-2 Pulse 5a, with absolute maximum ratings specifying SUP/SUPSW to GND at –0.3V to +42V. This allows direct connection to automotive battery without external TVS protection in most standard vehicle architectures, provided layout follows recommended grounding and decoupling practices outlined in the MAX16907RATE/V+ evaluation report.
Does the MAX16907RATE/V+ support fixed 5V output without external resistors?
Yes, the MAX16907RATE/V+ supports fixed 5V output by connecting the FB pin directly to the BIAS pin. This configuration eliminates external feedback resistors, reduces component count, and maintains 30µA standby current - a key advantage for low-power always-on automotive modules where the MAX16907RATE/V+ serves as primary system regulator.
What package type and thermal characteristics does the MAX16907RATE/V+ use?
The MAX16907RATE/V+ uses a 16-pin TQFN package (5mm × 5mm, 0.5mm pitch) with exposed thermal pad (EP). Its junction-to-ambient thermal resistance is 35°C/W on a 4-layer JEDEC-standard board, and junction-to-case is 2.7°C/W - enabling 3A continuous operation at +125°C ambient when EP is soldered to ≥4cm² contiguous copper ground plane per Maxim's layout guidelines.
How does the MAX16907RATE/V+ handle cold-crank undervoltage conditions?
The MAX16907RATE/V+ maintains up to 98% duty cycle during undervoltage transients (e.g., cold-crank down to 3.5V), ensuring uninterrupted 5V output regulation. Its dual-supply architecture (SUP and SUPSW) allows the control logic to remain powered while the high-side switch continues switching - a behavior confirmed in Figure 11 (Undervoltage Pulse Test) of the MAX16907RATE/V+ datasheet.
Is spread-spectrum operation enabled by default on the MAX16907RATE/V+?
No, spread-spectrum is not enabled by default on the MAX16907RATE/V+. It is a factory-configured option available only on the "S" version (e.g., MAX16907SATE/V+). The MAX16907RATE/V+ uses fixed 2.2MHz operation unless synchronized externally via FSYNC. When an external clock is applied, internal spread-spectrum is automatically disabled - preserving deterministic timing for synchronized systems.
