PhotoIC coupler for high speed communication
P
anasonic’s components spectrum is now extended by a PhotoIC coupler, a device that allows high speed signal transmission combined with an optical isolation between input and output. Main applications are in the field of measurement equipment and factory automation. The built-in light-receiving IC chip allows communication speeds of 50 Mbps (typical) and a guaranteed performance at a great temperature range from -40°C up to 105°C. With a CMTI of min. 15kV/µs, the PhotoIC coupler offers a high resistance against noise on the transmitted signal. All these great features are combined in a small package size of 4.4mm x 4.3mm x 2.1mm (SO6 5 pin). The PhotoIC coupler can be used in a wide range of applications. Placed in between a controller and a sensor, signals can be transmitted via a high variety of communication standards.

www.rencol-manufacturing.com R1275 2A Synchronus PWM DC/DC Converter R1275 Features:
• Operating Voltage 3.6V to 30V • Output Voltage Range 3.3V to 5.0V • Output Current Max. 2A • Feedback Voltage Tolerance 0.64V ±1.0% • Adjustable Oscillation Frequency 2.0MHz • External Synchronizable Clock Frequency 1.8 to 2.2MHz
• Spread Spectrum Clock Generator Diffusion Rate Typ. ±8%
he R1275 is a new advanced Step-Down Synchronous PWM DC/DC Converter belonging to the current R1270 / R1272 / R1273 flagship series, these products are designed for use in a wide range of consumer, industrial and automotive applications. It has a controller and high- and low- side N-channel MOSFETs assembled in a single package. There are a number of remarkable features to mention, such as an optional Spread-Spectrum Clock Generator, which causes the oscillator frequency to modulate mildly. As a result, it will decrease EMI noise interference amplitudes considerably, avoiding issues in nearby noise sensitive circuits. Another advantage of the R1275 is the option to synchronize the oscillator frequency. Especially in case the power supply consists of multiple DC/DC Converters, the independent switching frequencies can result in a significant noise in common ground wiring. By synchronizing the oscillator to an external clock signal, one is able to achieve a significant noise reduction in ground wiring.

• Adjustable Soft-start Time External Capacitor • Power Good Output NMOS Open-Drain • Safety Circuits UVLO, OVLO, Thermal, UVD, OVD, Hiccup Over Current Protection
As for automotive applications, the R1275 has a special feature to respond to a cranking condition. This phenomenon is the drop in the battery voltage when the car engine is started, it may result in an unstable output voltage of power management ICs in general. The R1275 responds by decreasing the oscillator frequency resulting in a constant output voltage level.
The device also features multiple protection circuits contributing to a safe operation of the application. As for excessive output currents, a Hiccup overcurrent protection is available. The circuit will be triggered when the output voltage drops during current limiting and shuts down the IC, protecting it from overheating. The IC will resume automatically to normal operation as soon the fault condition has been released.
A Power-Good output pin provides a fault signal to the system when the device is not ready for regular operation or when any of the protection circuits or states are active.
