R1207N Series STEP-UP DC/DC CONVERTER

PublishTime：2020-04-26

The R1207N Series are CMOS-based PWM control type step-up DC/DC converter ICs with low supply current.

Each of these ICs consists of an NMOS FET, a diode, an oscillator, a PWM comparator, a voltage reference unit,
an error amplifier, a current limit circuit, an under voltage lockout circuit (UVLO), an over-voltage protection circuit (OVP), a soft-start circuit, a Maxduty limit circuit, and a thermal shutdown protection circuit. This step-up DC/DC converter can be easily built with a few external components such as a coil, a resistor, and a capacitor. As the protection functions, the R1207N Series have a Lx peak current limit function, an over voltage protection (OVP) function, an under voltage lock out (UVLO) function and a thermal shutdown function.
The R1207N Series present the R1207N8xxA version that is optimized for the constant voltage power source, and the R1207N8xxB/C version that is optimized for driving the white LED with the constant current. The R1207N8xxB/C is an adjustable version that can change the LED brightness dynamically by using a 200Hz to 300kHz PWM signal toward the CE pin.
The R1207N Series are available in TSOT-23-6 package.
