Step Down DC/DC Controller

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. By Shanghai Belling Co, Ltd
