ACE150x

                                                                                         ACE150X                                               Technology Description 150KHz,2A, PWM Step-Down DC/DC Converter The ACE150x series are monolithic IC designed for a step-down DC/DC converter, and own the ability of driving 2A load without additional transistor. It saves board space. The Internal compensation makes feedback control having good line and load regulation without external design. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output switch. If current limit function occurs and VFB is down below 0.5V, the switching frequency will be reduced. The ACE150x series operate at a switching frequency of 150KHz. Other features include a guaranteed +4% tolerance on output voltage under specified input voltage and output load conditions, and +15% on the oscillator frequency. The output version included fixed 3.3V, 5V, 12V, and an adjustable type. The chips are available in a standard 8-lead SOP-8 package..
