com BL8501 Step down DC/DC controller OUTLINE The BL8501 is a CMOS-based PWM step-down DC-DC Converter controller.
The device can offer the following advantages: lower supply current and wider operating input-voltage range.
The BL8501 consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a soft-start circuit, a protection circuit, a PWM/VFM alternative circuit, a chip enable circuit, and detecting input voltage 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 can be adjust...
