Product details
Overview
MAX20414ATGA/V+ from Maxim Integrated is a dual-output automotive PMIC integrating a 750mA synchronous boost converter (OUT1, factory-set 3.8V–8.5V) and a 3A synchronous buck converter (OUT2, 0.8V–3.8V, factory-configurable or resistor-adjustable), operating at 2.2MHz with ±2% and ±1.5% output accuracy respectively, designed for infotainment head units and ADAS camera modules requiring compact, low-noise power delivery.
For engineers reviewing the MAX20414ATGA/V+ datasheet, MAX20414ATGA/V+ pinout, MAX20414ATGA/V+ application, or MAX20414ATGA/V+ equivalent, key selection considerations include its 2.2MHz fixed-frequency PWM mode for EMI control, spread-spectrum modulation, integrated low-RDS(ON) switches, and AEC-Q100 Grade-1 qualification for under-hood automotive use.
Technical Context
The MAX20414ATGA/V+ implements current-mode control for both converters, enabling stable operation across wide input (3.0V–5.5V) and output (OUT1: 3.8V–8.5V; OUT2: 0.8V–3.8V) ranges while supporting forced-PWM and skip modes to optimize efficiency from full load to light load. Its 2.2MHz switching frequency enables all-ceramic capacitor designs and reduces external component footprint.
It integrates independent enable inputs (EN1, EN2) and active-low reset outputs (RESET1, RESET2), supports soft-start on both channels, and includes overcurrent protection (OCP) and thermal shutdown with hysteresis-features essential for reliable operation in automotive infotainment and ADAS subsystems operating from -40°C to +125°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output automotive PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS650361RGER | Single 3.3V/1.2V buck-buck output; no boost channel; 2.25MHz switching; lower max current (1.5A/1.5A). | Lacks dedicated boost rail for displays/sensors; suited for MCU-only clusters without camera or backlight needs. | Select when only dual buck rails are required and board space allows larger external boost circuit. |

FAQ
What is the maximum output current capability of the MAX20414ATGA/V+ boost and buck channels?
The MAX20414ATGA/V+ provides up to 750mA from its synchronous boost converter (OUT1) and up to 3A from its synchronous buck converter (OUT2). These ratings are specified over the full -40°C to +125°C temperature range and assume proper thermal design with the exposed pad soldered to a sufficient copper area. Peak currents beyond these values may trigger overcurrent protection.
Does the MAX20414ATGA/V+ support programmable output voltage on both channels?
The MAX20414ATGA/V+ boost output (OUT1) is factory-preset to a fixed voltage within 3.8V–8.5V in 100mV steps and cannot be adjusted externally. The buck output (OUT2) supports either factory configuration (0.8V–3.8V in 25mV steps) or resistor-based adjustment via the FB2 pin-providing design flexibility without requiring reordering for minor voltage changes.
Is the MAX20414ATGA/V+ qualified for automotive applications?
Yes, the MAX20414ATGA/V+ is AEC-Q100 Grade-1 qualified (−40°C to +125°C ambient), with built-in protections including overcurrent, overtemperature, and undervoltage lockout. It is specifically designed for automotive infotainment and ADAS applications such as camera modules, head units, and digital clusters where reliability under harsh thermal and electrical conditions is mandatory.
How does the spread-spectrum feature of the MAX20414ATGA/V+ reduce EMI?
The MAX20414ATGA/V+ implements programmable spread-spectrum frequency modulation (SSFM) that dithers the 2.2MHz switching frequency by ±10%, spreading energy across a wider bandwidth and reducing peak radiated emissions by up to 10dB. This helps meet CISPR-25 Class 5 requirements in automotive environments without requiring additional shielding or ferrite beads.
What package type and thermal characteristics does the MAX20414ATGA/V+ use?
The MAX20414ATGA/V+ uses a 4mm × 4mm, 24-pin TQFN package with an exposed thermal pad (EP). The EP must be soldered to a PCB ground plane for effective heat dissipation and EMI suppression. Thermal resistance θJA is 36°C/W (with 2-layer 2oz Cu), enabling reliable 3A buck operation at +105°C ambient when properly laid out.
