DC-DC Regulators (DC to DC Converters) for Car-AV and Industry


Product Overview

DC-DC Regulator (also known as DC to DC Converter) for Car-AV and Industry, which provides EMI prevention in AM frequency band, is best suited for car navigation systems or car audio systems.

Features

  1. High-speed switching frequency allows use of AM radio EMI measures (two types).
  2. Power supply and high-side switch are combined on a single chip (ideal for use in USB applications). Overcurrent values can be set and continuously monitored using flag output.
  3. With load current monitoring function, voltage drop caused by factors such as cable resistance can be compensated (using the current feedback function) when supplying power to high-current-capacity loads (USB, etc.).

DC-DC converter for Car-AV and Industry


Measure 1: Switching operation beyond the AM band at a frequency of 2MHz allows EMI interference to be avoid and more compact peripheral components to be used.

DC-DC converter car-av noise avoidance

Easy design of the power supply by rich additional functions


Measure 2: Use of external synchronization* for frequency switching allows avoidance of interference with the desired frequency caused by harmonic components.
(* The frequency can also be changed with external resistance.)

DC-DC converter car-av noise avoidance

Easy design support for EMI measures of AM Band


Measure 3: PLL technology has been used to reduce output fluctuations during frequency switching from levels seen in order designs.
