Analog Devices Inc./Maxim Integrated MAX20049CATEA/VY+

Overview

MAX20049CATEA/VY+ from Analog Devices / Maxim Integrated is a compact quad power-supply IC for automotive camera modules. The device integrates two fixed-frequency step-down converters and two LDO regulators, allowing compact camera modules with lower minimum input operation to generate imager, serializer, logic, and memory rails from a single automotive or power-over-coax input.

As part of the MAX20049C product family, MAX20049CATEA/VY+ combines 4V to 17V input operation, two 500mA buck regulators, a 100mA high-PSRR LDO3, a 400mA LDO4, 2.2MHz PWM switching, voltage monitoring on all four rails, PGOOD fault reporting, and side-wettable TQFN packaging. For engineers reviewing the MAX20049CATEA/VY+ datasheet, MAX20049CATEA/VY+ pinout, MAX20049CATEA/VY+ application, or MAX20049CATEA/VY+ equivalent, this device is widely used in surround-view camera modules, rear-view camera modules, front camera electronics, power-over-coax imaging links, serializer boards, and compact automotive point-of-load supplies.

Technical Context

In vehicle camera electronics, MAX20049CATEA/VY+ uses two synchronous buck converters to create primary digital rails at up to 500mA each. The MAX20049C variant supports 4V to 17V input operation, helping the supply tolerate the voltage range expected in coax-powered and compact automotive camera installations.

LDO3 provides a 100mA high-PSRR low-noise rail for sensitive camera or analog loads, while LDO4 provides up to 400mA for secondary supplies. The datasheet output-selection structure supports 0.9V to 1.9V output range for buck regulator options and multiple fixed-output options for imager and serializer power trees.

MAX20049CATEA/VY+ is commonly used when a small 16-pin wettable-flank package must provide four monitored rails, 2.2MHz ceramic-capacitor switching, 180-degree out-of-phase buck operation, 500mV SUP1 hysteresis for long cables, PGOOD reporting, current-limit protection, and thermal shutdown.

Key Specifications

Pinout & Package

The MAX20049CATEA/VY+ pinout includes high-voltage supply inputs for the buck converters and LDO3, buck switch nodes, output sense pins, LDO outputs, PGOOD monitoring, enable or control pins, VBIAS, ground, and exposed-pad thermal connections.

For PCB design, the two buck loops should be kept compact, SUP input decoupling should be close to the IC, LDO output capacitors should be placed near their pins, and PGOOD/sense routing should avoid LX switching noise.

Key Features

• Two 500mA buck converters support camera digital rails.
• High-PSRR LDO3 improves sensitive image-chain supply noise.
• 400mA LDO4 supports secondary serializer, logic, or memory rails.
• 2.2MHz operation reduces passive size in camera modules.
• OV/UV monitoring and PGOOD support diagnostic supervision.
• Side-wettable TQFN and AEC-Q100 qualification support automotive assembly and reliability.

Applications

Equivalent & Alternatives

When evaluating a MAX20049CATEA/VY+ equivalent, engineers should compare input-voltage range, buck current, LDO current, output-voltage options, PGOOD behavior, side-wettable package, and automotive qualification.

Compared with MAX25249ATPA/VY+, MAX20049CATEA/VY+ uses a dual-buck plus dual-LDO architecture rather than three buck rails plus one LDO. MAX20049CATEA/VY+ vs MAX25250ATPA/VY+ selection depends on camera rail mix, input-voltage margin, PGOOD behavior, output-voltage option, and PCB footprint.

Quality

MAX20049CATEA/VY+ should be sourced as original Analog Devices / Maxim Integrated components through traceable supply channels. Quality checks may include wettable-flank TQFN inspection, top-mark validation, solderability testing, output-voltage verification, PGOOD behavior testing, and AEC-Q100 documentation review.

Production validation should include buck load transients, LDO noise performance, SUP input startup behavior, OV/UV fault thresholds, PGOOD timing, thermal rise, switching-node EMI, and current-limit response.

Availability

MAX20049CATEA/VY+ available at Aetrix Electronics and is suitable for automotive camera, surround-view, rear-view, front-view, power-over-coax, serializer, and compact point-of-load power systems.

Supply support may include volume procurement planning, scheduled delivery arrangements, traceable sourcing management, and long-term supply support for OEM, industrial electronics, automotive electronics, and embedded product programs. Sample and NPI supply support, as well as urgent in-stock supply support, can also be arranged for prototype builds, pilot runs, and time-critical production needs.

For production builds, confirming suffix-coded output voltages, package, input-voltage variant, lifecycle status, lead time, and sourcing continuity helps reduce procurement risk.
