The AN8017SA is a two-channel PWM DC-DC converter control IC that features low-voltage operation. This IC can obtain the step-up voltage 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 a miniaturized highly efficient potable power supply.
The Panasonic AN8017SA is a two-channel PWM DC-DC converter control IC designed for low-voltage applications with a minimum operating voltage of 1.8 V, allowing it to run on two dry batteries. It features a wide output frequency range from 20 kHz to 1 MHz and incorporates a high precision reference voltage circuit with an allowance of +2%.
The device includes several protection and control features such as a built-in timer latch short-circuit protection circuit, an under-voltage lock-out (U.V.L.O.) circuit starting at 1.67 V typical, and a dead-time variable function. It supports parallel operation and offers totem pole outputs with source currents up to -50 mA maximum and sink currents up to +80 mA maximum.
