1.8-volt 2-channel step-up, step-down, or inverting DC-DC converter control IC n Overview The AN8018SA is a two-channel PWM DC-DC con- verter control IC that features low-voltage operation. This IC can obtain the step-up, step-down and invert- ing voltages with a small number of external components. The minimum operating voltage is as low as 1.8 V so that it can operate with two dry batteries. In addition, since it uses the 16-pin surface mounting type package with 0.65 mm pitch, it is suitable for miniaturized highly efficient potable power supply. n Features

• Wide operating supply voltage range (1.8 V to 14 V)
• Incorporating a high precision reference voltage circuit (allowance: – 2%)
• Control in a wide output frequency range is possible (20 kHz to 1 MHz).
• Built-in wideband error amplifier (single gain bandwidth

10 MHz typical)

• Built-in timer latch short-circuit protection circuit (charge current 1.1 mA typical)
• Incorporating the under-voltage lock-out circuit (U.V.L.O.) (circuit operation-starting voltage 1.67 V typical)
• Dead-time is variable.
• Flatness of switching current can be obtained by staggering the turn-on timing of each channel.
• Built-in unlatch function When DT1 pin is low level, or DT2 pin is high level, independent turn-off is possible.
• Incorporating a on/off control function (active-high control input, standby mode current: 5 mA maximum)
• Parallel operation is possible.
• Output block
• Totem pole 1 output
• Output source-current: -50 mA maximum (Constant current output with a less supply voltage fluctuation is possible by connecting an external resistor to pin 11)
• Output sink-current: +80 mA maximum
• Open-collector 1 output
• Output current: 50 mA maximum n Applications
