DC DC Converters

The JCK2024S05 is a DC–DC converter from GSMK. It is a modern low voltage DC voltage regulator designed to accept a wide range of input supplies, and to provide one or two DC outputs of a very stable and adjustable voltage from 0.8 V to 5 V, and up to 5A per channel.

Application Field

The JCK2024S05 is designed primarily to supply one or two DC output voltages from a 2.7 V to 5.5 V input supply, for a variety of load currents (< 5A). It is suitable for applications such as computing, machines, industrial instruments, and automotive electronics. It is also perfect where very low voltage outputs are provided, such as the 0.8V level often used in microprocessors. The JCK2024S05 is designed to be very easy to use and requires very few external components.

Working Principle

The JCK2024S05 is a buck converter, with On-Off control. An internal switch is used to regulate the output voltage. When the power is switched on, the internal switch is activated and the inductor starts to build up a magnetic field, and this charges the output capacitor with the current output. The output voltage is then regulated by adjusting the timing when the switch is activated. The current output capability is mainly dependent on the inductor value, and the output voltage is set by a combination of feedback and resistive voltage dividers. The actual output voltage is monitored, and the regulator then adjusts the switch timing to ensure that the desired voltage is maintained.

The JCK2024S05 also features several protection systems, such as the short-circuit protection and over-temperature protection. It also has a low-standby current, making it suitable for applications where current consumption must be minimized. Furthermore, the JCK2024S05 uses a very efficient power topology that reduces the amount of internal heat generated, and thus the amount of input power wasted.

Conclusion

The JCK2024S05 is a sophisticated DC–DC converter from GSMK. It is designed to supply one or two low voltage DC outputs with a wide range of input voltages, and up to 5A per channel. Its working principle is based on buck converter topology with On-Off control, and multiple protection systems ensure its reliability and high efficiency. Therefore, the JCK2024S05 is an ideal choice for powering many applications, such as computing, machines, industrial instruments, and automotive electronics.
