DESCRIPTION
The SFH6345 is an optocoupler with a GaAlAs infrared emitting diode, optically coupled to an integrated photo detector consisting of a photo diode and a high speed transistor in a DIP-8 plastic package.
The device is similar to the 6N135 but has an additional faraday shield on the detector which enhances the input-output dV/dt immunity.
Signals can be transmitted between two electrically separated circuits up to frequencies of 2 MHz.
The potential difference between the circuits to be coupled should not exceed the maximum permissible reference voltages.

SFH6345 - High Speed Optocoupler, 1 Mbd, 15 kV/μs CMR, Transistor Output

GENERAL DESCRIPTION
 The XC9128/XC9129 series are synchronous step-up DC/DC converters with a 0.2Ω (TYP.) N-channel driver transistor and a synchronous 0.2Ω (TYP.) P-channel switching transistor built-in.
A highly efficient and stable current can be supplied up to 1.0A by reducing ON resistance of the built-in transistors.
With a high switching frequency of 1.2MHz, a small inductor is selectable making the series ideally suited for applications requiring low profile or space saving solutions.
With the MODE pin, the series provides mode selection of PWM control or PFM/PWM automatic switching control.
In the PWM/PFM automatic switching mode, the series switches from PWM to PFM to reduce switching loss when load current is small.
When load current is large, the series switches automatically to the PWM mode so that high\ efficiency is achievable over a wide range of load conditions.
The series also provides small output ripple from light to large loads by using the built-in circuit which enables the smooth transition between PWM and PFM.
When a voltage higher than the input voltage is applied to the output during shut-down, the input and the output become isolated making it possible for the IC to work in parallel with the likes of an AC adaptor.
