Description
The CRS02 TE85L,Q is a step-up switching regulator which is part of the S-8363 Series. This CMOS step-up regulator consists of a reference voltage source, an oscillation circuit, an error amplifier, a phase compensation circuit, a current limit circuit, and a start-up circuit. It boasts of PWM / PFM switching control features that help prevent decrease in efficiency caused by IC’s operating current. With a low operating voltage and input voltage range of 0.9V to 4.5V, the CRS02 TE85L,Q is suitable for various portable devices such as MP3 players, digital audio players, digital cameras, GPS, and wireless transceiver.
