A DC-DC converter is a device which converts direct-current (DC) electricity from one voltage level to another level, typically for the purpose of providing an isolated source of power and/or improving the efficiency of DC power supplies. JCB0312S15 DC-DC converter is a buck converter, employing switching mode power supply (SMPS) technology to convert input DC voltage to different output voltage levels.

Application Field and Working Principle

The JCB0312S15 converter is mainly used in industrial automation systems and control systems, providing efficient and reliable power solutions. The device is designed with low noise and safe isolation. Its operating frequency is typically up to 250kHz, which helps to reduce the size of the filter circuit and optimize the performance. The output voltage range is 10.8V-15.6V. The input voltage range is 10.8V-15.6V.

The buck converter utilizes two power MOSFETs for the power-switching function. It accepts an input voltage of 10.8V-15.6V, and outputs a precise voltage of 10.8V-15.6V, thanks to the high elements integration on-board. During operation, the MOSFETs work alternately by two different switching states (high and low). When the switch is in the high state, the input energy is stored in the inductor-capacitor circuit. When the switch is in the low state, the stored energy is allowing the inductor to release it at the output filter of the converter.

The input and output power transfer relationship of the JCB0312S15 converter is expressed in the Pout=f(Vin). So the output power can be adjusted based on the input voltage by changing the duty cycle of output\' signal. Since the switching frequency is further increased and the voltage stress on the power MOSFETs is limited, the switching losses are minimized. This results in high efficiency.

The JCB0312S15 converter adopts PFM control technique which offers quick response, tight DC regulation and low ripple voltage. The load regulation of this converter is typically 0.5% for 0-50% load and ±0.8% for 20-100% load. Its 0-100% transient response time is typically 5ms.

Protection and Self-Adjustment Ability

The JCB0312S15 converter provides a wide range of protections, including thermal shut down, input under-voltage lock-out, output over-voltage protection, and short-circuit protection. It integrates temperature sensor and current sensing circuit on the board, which will adjust the duty cycle of output signal and minimize the output ripple. All these protections and self-adjustment abilities ensure the JCB0312S15 converter provides the system with stable, safe, and reliable power supply.
