EMH7600
Battery Powered, High Efficiency Synchronous
DC/DC Boost Converter
General Description
EMH7600 is designed with high efficiency step up
DC/DC converter for portable devices applications.
It features with extreme low 26μA quiescent current
with no load which is the best fit for extending
battery life during the standby mode.
The start-up voltage is 0.93V typically with operating
voltage down to 0.7V. With Synchronous structure, it
does not need any external Schottky diode. The
peak current is limited to 1A for quick turn on. The
EMH7600 is available in MSOP-8 package.
This product can provide 500mA load current and
still maintained at least 70% efficiency and above
90% efficiency when at 100mA load current.
The EMH7600 is available in MSOP-8 package, With
RoHS compliance.

Function
Connecting to OUT to get +3.3V output,
Connecting to GND to get +5.0V output,
Using resistor network to set the output voltage from +1.8V to +5.5V.
Low-battery comparator input. Internally set at +1.195V+50mV to trip
Open-drain low battery comparator output. Output is low when VLBI is
<1.195V. LBO is high impedance during shutdown.
1.195V Output. In Case of driving load, Need R and C for stability
Shutdown input. “1” is enabled and “0”=shutdown
Ground Pin.
Switch Pin. Must be connected to Inductor.
Output Voltage Pin. This also provides bootstrap power to the IC.
