Description & Applications |
Buck DC-DC Converter IC ?Enables up to 2 A of load current (IOUT) with a minimum of external components. ? High efficiency: η = 95% (typ.) (@VIN = 5 V, VOUT = 3.3 V, IOUT = 0.7 A) ? Operating voltage range: VIN = 2.7 to 5.5 V ? Low ON-resistance: RDS (ON) = 0.18 Ω (high-side) / 0.12 Ω (low-side) typical (@VIN = 5 V, Tj = 25°C) ? High oscillation frequency: fOSC = 1500 kHz (typ.) ? Feedback voltage: VFB = 0.8 V ± 1% (@Tj = 25°C) ? Uses internal phase compensation to achieve high efficiency with a minimum of external components. ? Allows the use of a small surface-mount ceramic capacitor as an output filter capacitor. ? Housed in a small surface-mount package (PS-8) with a low thermal resistance. ? Soft-start time adjustable by an external capacitor |
