DC-DC converters are power electronic devices that convert a direct current (DC) input voltage to a different direct current (DC) output voltage.The JCE0312D12 is an isolated, open-frame DC/DC converter designed to offer maximum flexibility in the application field. It has ultra-wide 4.5 to 48V input and single, dual, triple output configurations. It meets the requirements of railway and automotive applications which demand a high level of operational reliability.

The JCE0312D12 provides high efficiency, LED over voltage protection (OVP), over current protection (OCP) and an output over voltage protection (OVP) option. It has an enviable power density of 48W/in? with a value from 0.20W to 48W in a 25.4mm x 25.4mm housing or 45.00W/in? with higher outputs up to 200W in standard industry packaging. It is an ideal choice for end applications such as cars, trains, mobile devices, portable equipment, medical type, and 11th generation product.

The JCE0312D12 utilizes advanced power conversion technology and fixed frequency, 100KHz voltage-mode PWM control that offers fast transient response with 10μs internal compensation and quiet operation. The device is packaged in an appropriate, robust package for impedance and EMI control. Floating output voltage, built-in EMI filer, output trim up/down through an external resistor, over current limit, and over voltage protection are just some of the features which make this device suitable for all types of demanding application. The power factor correction (PFC) feature ensures superior line and load regulation.

The JCE0312D12 is unusually compact and its low profile is ideal for applications with limited space. In addition, it is easy to mount since it has two widely spaced mounting ears that can fit into anything. Its input/output interfaces are designed for wide compatibility, thus allowing the user to connect to almost any type of circuit. Its secure terminals and insulation also offer extra protection.

Its working principle lies in the use of an advanced voltage-mode Pulse Width Modulation (PWM) system, where an on/off switch, the power semiconductor switch, controls the power flow from the input source to the output. The PWM switching signal supplies the switch with a logic signal that turns it ON and OFF at a frequency determined by the voltage mode loop. The output voltage is determined according to the duty cycle.

The JCE0312D12 offers state of the art system monitoring and operational safety. The module automatically shuts down in the event of over temperature or over current, and its continuous short circuit protection features provides reliable protection to the module itself and to the connected loads. The unit\'s integrated LED indicator can be programmed to indicate the module\'s operational states.

The JCE0312D12 is a high-end DC/DC converter solution designed to enable higher efficiency, better thermal performance, lower noise and a longer product life cycle. Its multiple configurations and integrated protection features make it an ideal choice for application requiring high-end performance and high-end safety.
