PWM Step-up DC/DC Converter Controller  
NO. EA-064-071207  
R1210Nxx2x SERIES  
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.  
FEATURES  
External Components .......................................Only an inductor, a diode, a capacitor, and a transistor  
Standby Current................................................Max. 0.5µA  
Low Temperature-Drift Coefficient of Output Voltage Typ. ±100ppm/°C  
Output Voltage ..................................................Stepwise Setting with a step of 0.1V in the range of  
2.2V to 6.0V  
Two choices of Basic Oscillator Frequency ......100kHz (xx2C), 180kHz (xx2D)  
Output Voltage Accuracy...................................±2.5%  
Small Package..................................................SOT-23-5 (Mini-mold)  
Low Ripple, Low Noise  
Oscillator Start-up Voltage ................................Max. 0.8V  
APPLICATIONS  
Power source for battery-powered equipment.
