Product details

Overview

MAX16935BAUER/V+T from Maxim Integrated is a 3.5A, current-mode synchronous step-down DC-DC converter with integrated high-side and low-side MOSFETs, designed for automotive power supplies operating from 3.5V to 36V input. It delivers fixed 5V output with ±2% accuracy, supports resistor-programmable switching frequency up to 2.2MHz, and features 28µA quiescent current at no load-enabling always-on functionality in vehicle infotainment systems.

For engineers reviewing the MAX16935BAUER/V+T datasheet, MAX16935BAUER/V+T pinout, MAX16935BAUER/V+T application, or MAX16935BAUER/V+T equivalent, key selection criteria include AEC-Q100 qualification, 98% max duty cycle for cold-crank support, FPWM/skip mode control via FSYNC, 180° out-of-phase SYNCOUT for cascaded supplies, and thermal shutdown with automatic recovery.

Technical Context

The MAX16935BAUER/V+T implements current-mode control with internal slope compensation and cycle-by-cycle current limiting. Its dual-supply architecture separates logic (SUP) and switch (SUPSW) rails, enabling stable operation during undervoltage transients down to 3.5V while maintaining 98% duty cycle.

It integrates a 5V BIAS linear regulator (4.7–5.4V output), supports external Schottky diode for efficiency optimization, and provides programmable soft-start (5.6–12ms), spread-spectrum EMI reduction (±6%), and automatic LX slew-rate adjustment (4ns/8ns based on f_SW).

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	3.5V to 36V (42V transient tolerant); supports automotive cold-crank and load-dump conditions.
Output Current	3.5A continuous; peak LX current limit 4.2–6.2A enables robust overload handling.
Output Voltage	Fixed 5V (±2% accuracy); also adjustable 1V–10V via FB resistive divider.
Quiescent Current	28µA at no load; enables ultra-low-power standby in always-on automotive modules.
Switching Frequency	220kHz–2.2MHz (resistor-programmable); synchronizable to external clock ±20%.
Operating Temperature	−40°C to +125°C; qualified per AEC-Q100 Grade 1 for under-hood deployment.
Duty Cycle Max	98%; maintains regulation during severe input undervoltage events (e.g., engine cranking).

Pinout & Package

MAX16935BAUER/V+T is housed in a 16-pin, 5mm × 5mm TQFN-EP package with exposed pad for thermal dissipation. Pin mapping follows the standard TQFN layout with PGND and EP connected to system ground plane.

Pin/Terminal	Circuit Role	Design Meaning
1 – SYNCOUT	Open-drain clock output	180° out-of-phase signal relative to internal oscillator; enables synchronized multi-converter cascading.
2 – FSYNC	Mode/frequency control input	Selects skip mode (AGND) or FPWM (BIAS/external clock); critical for EMI-sensitive RF supply design.
3 – FOSC	Frequency programming node	Resistor-to-AGND sets f_SW; e.g., 12kΩ yields 2.2MHz for compact magnetics and low output capacitance.
4 – OUT	Regulated output	Delivers 5V/3.5A; powers downstream circuitry and supplies internal bias when V_OUT ≥ 3V.
5 – FB	Feedback sensing input	Monitors output via resistive divider; regulates to 1.0V reference (0.99–1.015V) for ±2% accuracy.
6 – COMP	Error amplifier output	Connects RC compensation network to stabilize loop response across full load and temperature range.
7 – BIAS	Integrated LDO output	5V ±0.3V regulated supply for internal analog blocks; bypassed with 1µF ceramic capacitor.
8 – AGND	Analog ground reference	Separate ground for precision feedback and error amplifier; must be star-connected to PGND.
9 – BST	High-side gate driver supply	Bootstrap capacitor (0.1µF) between BST and LX enables efficient high-side MOSFET drive.
10 – EN	Enable control input	3.3V–42V compatible; asserts device from shutdown (5µA I_SHDN) into active regulation.
11 – SUP	Logic supply input	Powers internal LDO and logic; bypassed with 4.7µF ceramic capacitor to PGND.
12 – SUPSW	Switch supply input	Powers high-side/low-side drivers; bypassed with 0.1µF + 4.7µF ceramics to PGND.
13–14 – LX	Switching node	Connects to external Schottky diode cathode and inductor; slew rate auto-adjusted for EMI/efficiency trade-off.
15 – PGND	Power ground return	Primary return path for high-current switching paths; connects to exposed pad (EP).
16 – PGOOD	Open-drain power-good flag	Asserts high when V_OUT > 95% of regulation; deasserts at <92%; enables safe power sequencing.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar step-down converter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX16939BAUER/V+T	Lower OVP threshold (105% vs. 107% for MAX16935); identical pinout, specs, and package.	Better suited for systems requiring tighter output overvoltage clamp, e.g., FPGA I/O banks with narrow VCC tolerance.	Select MAX16939BAUER/V+T only if tighter OVP is required; otherwise MAX16935BAUER/V+T offers broader margin.
LM61480QRNXTQ1	4.5A rating, 3.5V–36V input, 2.1MHz max f_SW, but no BIAS LDO or SYNCOUT; requires external bootstrap capacitor.	Lacks integrated 5V BIAS regulator and 180° clock output-unsuitable for cascaded multi-rail designs or bias-sensitive analog sections.	Choose LM61480QRNXTQ1 only for higher-current needs where BIAS and SYNCOUT are unused; MAX16935BAUER/V+T provides superior integration.

Compared with MAX16939BAUER/V+T, the MAX16935BAUER/V+T offers higher OVP threshold for less aggressive clamping; versus LM61480QRNXTQ1, it delivers greater integration (BIAS LDO, SYNCOUT, FPWM/skip control) at the cost of 0.5A lower current rating-making it optimal for compact, feature-rich automotive point-of-load designs.

FAQ

What is the maximum input voltage the MAX16935BAUER/V+T can withstand during load-dump events?

The MAX16935BAUER/V+T supports up to 42V input during load-dump transients (t < 1s), as specified in its Absolute Maximum Ratings. This 42V tolerance eliminates the need for external TVS diodes in most automotive 12V systems, simplifying front-end protection design while ensuring robustness against ISO 7637-2 Pulse 5a events. The device remains fully functional after such transients.

Does the MAX16935BAUER/V+T require an external Schottky diode, and why?

Yes, the MAX16935BAUER/V+T requires an external Schottky diode connected from LX to AGND. Although it integrates high-side and low-side MOSFETs, the diode improves light-load efficiency by providing a low-loss freewheeling path-especially critical in skip mode. The datasheet explicitly states this requirement for optimal performance and thermal management across the full 3.5A load range.

How does the FSYNC pin control operating mode in the MAX16935BAUER/V+T?

The FSYNC pin selects between skip mode and forced-PWM (FPWM) mode: connecting FSYNC to AGND enables skip mode for highest light-load efficiency, while pulling FSYNC to BIAS or applying an external clock forces FPWM operation across all loads. This pin directly controls the low-side MOSFET's behavior, enabling deterministic frequency for EMI-sensitive applications like RF transceivers powered by the MAX16935BAUER/V+T.

What is the purpose of the SYNCOUT pin on the MAX16935BAUER/V+T, and how is it used?

The SYNCOUT pin on the MAX16935BAUER/V+T provides an open-drain 180° out-of-phase clock signal relative to the internal oscillator. It is used to synchronize multiple MAX16935BAUER/V+T devices in interleaved configurations-reducing input/output ripple and increasing total available current. A pull-up resistor (100Ω–1kΩ) to OUT sets proper logic levels for 2MHz operation, enabling scalable power delivery in complex automotive ECUs.

Is the MAX16935BAUER/V+T pin-compatible with other variants in the MAX16935/MAX16939 family?

Yes, the MAX16935BAUER/V+T is pin-compatible with all members of the MAX16935/MAX16939 family-including MAX16939BAUER/V+T and MAX16935CAUER/V+T-in the same TQFN-EP package. Electrical differences (e.g., OVP threshold, quiescent current) do not affect pin function or layout, allowing drop-in replacement for qualification reuse or minor spec adjustments without PCB revision.
