www.DataSheet4U.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 adjusted with external resistors. FEATURES Range of input Voltage: 3.
