MAX17625ATA+T Switching Voltage Regulators 2.9V-to-5V Input, 1A , 1.5V-to-3.3V output DC-DC Converter
Maxim Integrated MAX17625 Synchronous Step-Down Converters
Maxim Integrated MAX17625 Synchronous Step-Down Converters have integrated MOSFETs and compensation components. These operate over a 2.7V to 5.5V input voltage range. The MAX17625 supports up to 700mA load current and allow the use of small, low-cost input and output capacitors. The output voltage can be adjusted from 0.8V to 3.3V. When the EN pin is asserted, an internal power-up sequence ramps up the error-amplifier reference, resulting in output-voltage soft-start. The FB pin monitors the output voltage through a resistor divider. The devices select either PFM or forced-PWM mode depending on the state of the MODE pin at power-up. By pulling the EN pin to low, the devices enter shutdown mode and consume only 0.1µA (typ) of standby current. FEATURES
