What is the low voltage coil-integrated DC/DC converter “XCL series”?
The low-voltage coil-integrated DC/DC converter “XCL series” is an ultra-compact DC/DC converter that integrates a coil and control IC using Torex’s unique technology.
The coil-integrated structure maximizes the performance of the DC/DC converter and realizes compatibility with keywords such as space-saving, high efficiency, low noise, high heat dissipation, and low cost.
With only two external capacitors, it is as easy to use as an LDO and can be used in many applications such as products with a tight board area or applications that are strict with RF noise.

Features of Low Voltage Coil Integrated DC/DC Converter “XCL Series”
1. Low voltage, low power consumption, and low price

- Realize total cost reduction (BOM, board, mounting) by reducing not only the product price but also the board area and the number of parts.
- Achieves low power consumption of the entire system and long battery life.
- Lineup of step-up/step-down DCDC converters.
2. Reduction of unwanted radiation noise (EMI)
- Uses coils with low magnetic flux leakage
- Coil characteristics are adjusted for the coil-integrated DC/DC converter “XCL series”
- Optimizing DC/DC operation
- Pin position and construction take the current path into consideration
- Near magnetic field noise is slight, so the possibility of interfering to peripheral devices is small

3. A diverse lineup that supports a wide range of usage environments, such as battery-powered devices and IoT devices
- Lineup of 4 package types according to product specifications
– “Pocket Type” space-saving mounting area, high efficiency, ultra-compact, low EMI noise, and compatible up to about 1A
– “Stack Type” aiming to simplify the production line and reduce costs
– “Multiple Type” with a built-in large coil that can handle large currents
– “Cool Post Type” that enables high heat dissipation by Cu post structure
