R1224N SERIES

PWM/VFM step-down DC/DC Converter

NO.EA-096-061102

OUTLINE

The R1224N Series are CMOS-based PWM step-down DC/DC Converter controllers with low supply current.

Each of these ICs consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a

phase compensation circuit, a soft-start circuit, a protection circuit, a PWM/VFM alternative circuit, a chip enable

circuit, resistors for output voltage detect, and input voltage detect circuit. A low ripple, high efficiency step-down

DC/DC converter can be easily composed of this IC with only several external components, or a power-transistor,

an inductor, a diode and capacitors. Output Voltage is fixed or can be adjusted with external resistors (Adjustable

types are without PWM/VFM alternative circuit).

With a PWM/VFM alternative circuit, when the load current is small, the operation is automatically switching

into the VFM oscillator from PWM oscillator. Therefore, the efficiency at small load current is improved. Several

types of the R1224Nxxx, which are without a PWM/VFM alternative circuit, are also available.

If the term of maximum duty cycle keeps on a certain time, the embedded protection circuit works. The

protection circuit is Reset-type protection circuit, and it works to restart the operation with soft-start and repeat

this operation until maximum duty cycle condition is released. When the cause of large load current or something

else is removed, the operation is automatically released and returns to normal operation.

Further, built-in UVLO function works when the input voltage is equal or less than UVLO threshold, it makes

this IC be standby and suppresses the consumption current and avoid an unstable operation.
