GENERAL DESCRIPTION
The AMS6104 is an adjustable step-up DC/DC converter with a 1Amp internal switch. The low quiescent current of typical
300µA, makes AMS6104 attractive for battery operated applications. AMS6104 operates at switching frequencies of 500 kHz
allowing for easy filtering and low noise. The reference voltage is set at 1.23V. Internally compensated and internal soft-start
minimizes the number of external components necessary. It operates from 1.3V to 15V supply and it is thermally and over
current protected. The AMS6104 is available in SOT23-5 leads package.

DESCRIPTION
Feedback Input. Connect a resistive voltage divider from the output voltage to FB to set the
output voltage. The feedback regulation threshold is 1.23V.
Ground
High side of the Switch transistor. The Low side of the Switch transistor is internally
connected to GND
Internal Power Input. VCC powers the internal circuitry. If the input source remains above
3.0V, VCC can be connected to the input source to reduce power consumption.
Enable. A high voltage at EN turns on the converter, and a low voltage turns it off. When
not used, connect EN to the input source for automatic startup. If EN is driven over 6V,
place a 10 kto 47kresistor in series with EN.
3.3V to 5.0V application
