Product details
Overview
The MAX16904SATB60/V+T from Maxim Integrated is a synchronous buck DC-DC converter delivering 600mA output with fixed 6.0V output voltage, +3.5V to +28V input range, 2.1MHz switching frequency, and spread-spectrum EMI reduction. It features PGOOD monitoring, 97% dropout operation, and AEC-Q100 qualification for automotive power rails.
For engineers reviewing the MAX16904SATB60/V+T datasheet, MAX16904SATB60/V+T pinout, MAX16904SATB60/V+T application, or MAX16904SATB60/V+T equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade thermal and transient performance, and two rigorously cross-checked alternative parts for 6V buck conversion in harsh-environment systems.
Technical Context
The MAX16904SATB60/V+T implements current-mode control with integrated high-side (400–800mΩ RDS(ON)) and low-side (250–450mΩ) MOSFETs, enabling stable regulation down to 97% duty cycle during input dropout. Its 2.1MHz internal oscillator supports three modes: SKIP (25μA IQ), forced PWM, and external synchronization - all compatible with the 6.0V output configuration.
Spread-spectrum modulation (+6% frequency deviation) is enabled per ordering code "S", reducing radiated EMI without compromising AM-band immunity. The device monitors output quality via open-drain PGOOD (91–94% trip threshold) and includes thermal shutdown at 175°C with 15°C hysteresis, ensuring robustness in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 6.0V ±2.5% (fixed-frequency mode), ±4.0% (SKIP mode); enables direct replacement of 6V LDOs with higher efficiency. |
| Input Voltage Range | +3.5V to +28V continuous; tolerates +42V transients ≤1s - supports 12V/24V automotive battery rails including cold-crank events. |
| Max Output Current | 600mA minimum guaranteed; peak current limit 1.05A - sufficient for powering microcontrollers, sensors, and CAN transceivers. |
| Switching Frequency | 2.1MHz typical (1.925–2.275MHz); allows use of compact 3.3–5.6µH inductors and reduces output ripple without AM-band interference. |
| Quiescent Current | 25μA typical in SKIP mode at no load - extends battery life in always-on vehicle modules like telematics and body controllers. |
| Operating Temperature | -40°C to +125°C ambient; AEC-Q100 qualified - validated for engine bay, transmission, and ADAS ECU placement. |
| Package | 10-pin TDFN-EP (3mm × 3mm × 0.75mm); exposed pad soldered to PGND - achieves θJA = 41°C/W for thermally constrained PCBs. |
Pinout & Package
MAX16904SATB60/V+T is housed in a thermally enhanced 10-pin TDFN-EP package (outline 21-0137, land pattern 90-0003) with an exposed pad connected to PGND for optimal heat dissipation in automotive layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BST | Bootstrap capacitor node | Drives high-side FET gate; requires 0.1µF ceramic capacitor between BST and LX to sustain >97% duty cycle in dropout. |
| SUP | Main input supply | +3.5V to +28V input; connect 4.7µF ceramic capacitor directly to PGND; withstands +42V transients. |
| LX | Switching node | Connects to inductor; high-impedance when off; critical path for minimizing EMI radiation and layout loop area. |
| PGND | Power ground return | High-current return for LX and SUP; must be tied to exposed pad and kept separate from analog GND until single-point connection at OUTS capacitor. |
| OUTS | Voltage feedback sense | Monitors regulated output; bypass with ≥10µF X7R ceramic to PGND; determines output accuracy and stability. |
| PGOOD | Open-drain status signal | Pulls low when VOUT < 91% nominal; requires external 20kΩ pull-up; used for system power sequencing and fault detection. |
| SYNC | Mode control and sync input | GND/unconnected → SKIP mode; BIAS or clock → forced PWM; enables dynamic efficiency optimization in real-time systems. |
| BIAS | Internal logic supply | +5V regulated output; powers internal circuitry; bypass with 2.2µF ceramic to GND; supplies SYNC and EN bias. |
| GND | Analog reference ground | Low-noise reference for error amplifier and bandgap; connect to PGND only at OUTS capacitor cathode to avoid noise coupling. |
| EN | Enable control | High-voltage compatible (3.3V–42V logic); drives high for operation; no internal pullup/pulldown to minimize leakage. |
Key Features
| Feature | Design Value |
|---|---|
| Spread-spectrum EMI reduction | +6% frequency modulation enabled on MAX16904SATB60/V+T - lowers peak radiated emissions without requiring external filters or shielding. |

| Dropout operation | 97% maximum duty cycle - maintains regulation during 6V battery sag (e.g., cold-crank to 5.5V input) while delivering full 600mA. |
| Integrated power-good signaling | PGOOD with 10µs debounce and 91–94% threshold - provides deterministic power sequencing for downstream MCUs and FPGAs. |
| AEC-Q100 qualification | Qualified for automotive Grade 1 (-40°C to +125°C) - meets stress testing requirements for engine control, infotainment, and ADAS applications. |
