AT7109 Dual 1.5MHz, 800mA Synchronous Step-Down Converter Immense Advance Tech. FEATURES z z z z z z z z z DESCRIPTION The AT7109 is a dual channel, constant frequency, synchronous step-down DC/DC converter. Intended for low power applications, it operates from 2.5V to 5.0V input voltage range and has a constant 1.5MHz switching frequency, enabling the use of tiny, low cost capacitors and inductors 1mm or less in height. Each output voltage is adjustable from 0.6V to 4.2V. Internal synchronous 0.35Ω, 1A power switches provide high efficiency without the need for external Schottky diodes. The current mode operation achieves fast line and load transient response.
