FEATURES The BL8523 is a CMOS-based PWM step-down DC-DC Controller. The device offers the following advantages: lower supply current and wider operating input-voltage range. The BL8523 consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a soft-start circuit, a protection circuit, a PWM/PFM alternative circuit, a .
The BL8523 is a CMOS-based PWM step-down DC-DC Controller. The device offers the following advantages: lower supply current and wider operating input-voltage range.
The BL8523 consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a soft-start circuit, a protection circuit, a PWM/PFM alternative circuit, a Chip Enable circuit, and under voltage lockout circuit. A low ripple, high efficiency step-down DC-DC converter can be easily composed of this IC. Output Voltage can be adjusted with external resistors.
Range of Input Voltage: 3V~16V
