The MAX1556ETB+T is a 16µA quiescent current, 1.2A PWM step-down DC to DC converter in 10 pin TDFN package. It is a high efficiency, low-quiescent operating current, low dropout and minimal (27µA) quiescent current in dropout make this converter ideal for powering portable devices from 1-cell Li-ion or 3-cell alkaline/NiMH batteries. The MAX1556 delivers up to 1.2A and has pin selectable 1.8V, 2.5V and 3.3V outputs and is also adjustable. The MAX1556 contain a low on-resistance internal MOSFET switch and synchronous rectifier to maximize efficiency and dropout performance while minimizing external component count. A 1MHz PWM switching frequency keeps components small. Both devices also feature an adjustable soft-start to minimize battery transient loading.
● Supply voltage range is 2.6V to 5.5V
● Operating temperature range from -40°C to 85°C
● Voltage positioning optimizes load transient response
● Low shutdown current is 0.1µA
● No external schottky diode required
