Infineon TLF35584 Series DC/DC Converter, 5.5V Maximum Input Voltage, 1300mA Maximum Output Current - TLF35584QVVS1XUMA2


This DC/DC converter is a vehicle-grade power regulator intended to maintain stable voltages in automotive electronic systems. It operates in a buck-boost topology to accommodate varying vehicle bus levels, handling two outputs with selectable voltage states and designed for use across a broad temperature range in safety-conscious automotive environments.

Features and Benefits:


• Wide input range supports 3-5.5 V for variable supply rails
• Dual outputs provide selectable 3.3 V and up to 5 V delivery
• Peak output current capability of 1300 mA supports power-hungry loads
• Switching frequency up to 2.2 MHz enables Compact passive components
• Operating range from −40 to 150 °C suits harsh under‑bonnet conditions
• 48‑pin VQFN package allows high pin density and thermal conduction

Applications


• Suitable for automotive safety-system power distribution
• Ideal for infotainment modules requiring dual rails
• Used with sensor clusters needing a stable 3.3 V supply
• Can be used for ECU subsystems with limited PCB area
• Suitable for battery‑assisted electronics with fluctuating input

What protection or automotive qualification does it support?


It conforms to ISO 26262 functional safety standards for automotive power devices.

How many outputs are available and how are voltages chosen?


It offers two outputs with selectable voltage settings including a 3.3 V option and outputs up to 5 V.

What are the limits for input voltage operation?


The regulator accepts input voltages from 3 V up to a maximum of 5.5 V.

What packaging and pin count should I plan for on the PCB?


The device comes in a 48‑pin VQFN package requiring footprint and thermal considerations for high‑density layouts.

What performance should be expected for switching speed and current delivery?


The converter operates at up to a 2.2 MHz switching frequency and can deliver up to 1300 mA per output.
