ACE7215C
1.5A 1.5MHz Synchronous Buck Converter
Description
The ACE7215C is a high-efficiency monolithic synchronous buck regulator using a constant frequency,
current mode architecture. The device is available in an adjustable version. Supply current with no load is
40uA and drops to <1uA in shutdown. The 2.5V to 6V input voltage range makes the ACE7215C ideally
suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation,
extending battery life in portable systems. PWM/PFM mode operation provides very low output ripple
voltage for noise sensitive applications.
Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and
capacitors. Low output voltages are easily supported with the 0.6V feedback reference voltage.
The ACE7215C is available in SOT23-5 and DFN2*2-6L package.
