The AN8015SH is a single-channel DC-DC converter control IC using the PWM method. This IC can provide any one output type from among step-down, step-up and inverting output. Its operating supply voltage range is wide and its consumption current is small. In addition, since it uses the 10-pin surface mounting type package with 0.5 mm pitch, it is suitable for highly efficient miniature potable power supply, especially for a negative output power supply.
