R1210Nxx2x SERIES PWM Step-up DC/DC Controller NO.EA-064-181214 OUTLINE The R1210Nxx2C/xx2D Series are CMOS-based PWM step-up DC/DC Converter controllers, with high accuracy, low supply current. Each of the R1210Nxx2x Series consists of an oscillator, a PWM circuit, a reference voltage unit, an error amplifier, phase compensation circuit, resistors for voltage detection, a chip enable circuit, a controller against drastic load transient and an output voltage detector. A low ripple, high efficiency step-up DC/DC converter can be composed of this IC with only four external components, or an inductor, a diode, a transistor and a capacitor. The R1210Nxx2x Series can detect drastic change of output voltage with a circuit controller, the load transient response is improved. Each of the R1210Nxx2x Series has a driver pin, or ‘EXT’ pin for external transistor. By connecting a power transistor with low ON-resistance to EXT pin, a large current flows through an inductor, thus, large output current can be supplied. The built-in chip enable circuit can make the standby mode with ultra low quiescent current. Since the package for these ICs is small SOT-23-5, high density mounting of the ICs on board is possible.

We are making our continuous effort to improve the quality and reliability of our products, but semiconductor products are likely to fail with certain probability. In order to prevent any injury to persons or damages to property resulting from such failure, customers should be careful enough to incorporate safety measures in their design, such as redundancy feature, fire containment feature and fail-safe feature. We do not assume any liability or responsibility for any loss or damage arising from misuse or inappropriate use of the products. 7. Anti-radiation design is not implemented in the products described in this document. 8. The X-ray exposure can influence functions and characteristics of the products. Confirm the product functions and characteristics in the evaluation stage. 9. WLCSP products should be used in light shielded environments. The light exposure can influence functions and characteristics of the products under operation or storage. 10.
