AD8561 pinout datasheet


The AD8561 is a single 7 ns comparator with separate input and output sections. Separate supplies enable the input stage to be operated from ±5 V dual supplies and +5 V single supplies. Fast 7 ns propagation delay makes the AD8561 a good choice for timing circuits and line receivers. Propagation delays for rising and falling signals are closely matched and track over temperature. This matched delay makes the AD8561 a good choice for clock recovery, since the duty cycle of the output will match the duty cycle of the input.

The AD8561 has the same pinout as the LT1016, with lower supply current and a wider common-mode input range, which includes the negative supply rail. […]

CR6202 Datasheet PDF – Switching Power Supply Controller IC

Part Number: CR6202

Function: Switching Power Supply Controller IC

Package: DIP 8 Pin Type

Manufacturer: Chip-Rail, Power Rail


CR6202 datasheet



CR6202 is a high-performance current mode flyback PWM controller for AC/DC transformer with high performance and price ratio,  which supplies continuous output power of 5W within the range of wide-voltage between 85V and265V, the output power of peak value can be  up  to  18W. The combination of optimized reasonable circuit design and bipolar facture technology with high performance and price ratio economizes the whole cost ultimately. The power controller can be applied to the typical flyback circuit topology so as to form a simple AC/DC transformer.


1. Set-in high-voltage power switch transistor of 700V and few peripheral components
2. With the modulation of lock pulse width, the testing is according to the pulse limit current.
3. Inner-built ramp and anti-feedback compensation function
4. Set-in heat protection circuit
5. Few peripheral components
6. Low startup and operating current
7. VCC over-voltage automatic limit
