Description

The ACE707P integrated PFM-mode synchronous step- up converter, only need one inductor and two

capacitor. Because of boost proprietary design, it starts up at very low input voltage down to 850mV;

make it an ideal choice for single cell alkaline/NiMH battery operations.

ACE707P integrates stable reference circuits and trimming technology, so it can afford high precision and

low temperature-drift coefficient of the output voltage.

The ACE707P integrates a reference voltage source, an oscillator, and a comparator, enabling products

with a low ripple over a wide range, high efficiency and ultra-low no-load current, high output current.

The ACE707P is available in SOT23-3&SOT23-5 packages (Rohs & HF)
