PWM Step-up DC/DC Converter

The R1210N Series are CMOS-based PWM Step-up DC/DC Converter, with high accuracy, low supply current. Each of the R1210N 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. Further, includes a controller against drastic load transient, a control Transistor with low ON-Resistance, LX Switch and a protection circuit for LX Switch and an output voltage detector. R1210N Series contain further a circuit for changeover Oscillator frequency each. A low ripple, high efficiency Step-up DC/DC converter CAN be composed of this IC with only three external components, or an inductor, a Diode and a capacitor. The R1210N Series CAN detect drastic change of output voltage with a circuit controller. The load transient response is improved compared with current model, furthermore the R1210N Series have another function, that is, when the load current is small, Oscillator frequency is decreased by a circuit for switching Oscillator frequency from Typ. 100kHz to 35kHz, therefore, supply current is reduced. 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.
