Frequently Asked Questions
How many output rails does LM34904 provide?
The LM34904 provides four independent regulated outputs: two synchronous buck converters (500mA each) and two LDOs (300mA each). This covers typical FPGA/processor needs for core, I/O, auxiliary, and analog supply rails in a single IC.
What is the input voltage range of LM34904?
The LM34904 accepts 3V to 5.5V input, compatible with standard 3.3V and 5V system rails. The buck converters operate at 2MHz fixed frequency, enabling small external inductors and capacitors for compact designs.
Does LM34904 support power sequencing?
Yes, the LM34904 includes built-in power-up sequencing with configurable enable pins for each output. This ensures proper boot sequence for FPGAs and processors that require specific voltage rail ordering during power-up.
What is the efficiency of LM34904 buck converters?
The synchronous buck converters achieve up to 95% efficiency at typical loads, significantly reducing heat generation compared to linear regulators. The integrated synchronous FETs eliminate the need for external Schottky diodes.
