SGM6602  
20V Output Voltage Boost Converter  
GENERAL DESCRIPTION  
FEATURES  
The SGM6602 is a boost converter integrated with both  
the PWM switch and the isolation switch. This device  
accepts an input voltage range of 1.8V to 5.5V. And the  
output voltage can reach a maximum of 20V. The  
output of this device has the 9V or 12V default output  
voltage when the FB pin is connected to VIN pin. This  
device has a switching current limit of 900mA (TYP). It  
is highly efficient with peak efficiency of 85% at 3.6V  
input and 12V output when in operation. In shutdown  
mode, the input and output are truly disconnected.  
● 1.8V to 5.5V Input Voltage Range  
● Up to 20V Output Voltage  
● Up to 85% Efficiency  
● 900mA (TYP) Switch Current  
● Internal 5ms Soft-Start Time  
● Less than 1μA Ultra-Low Shutdown Current  
● Integrated Isolation Switch  
● Power-Save Mode at Light Load  
● Input and Output are Disconnected during  
Shutdown  
● Output Short-Circuit and Over-Voltage  
Protection  
This device is targeted at the applications with high  
voltage and small solution size requirements. The  
1.1MHz switching frequency allows this device to use  
small external components. The packages of this  
device also allow it to have a tiny solution size. The  
protection features involve the output short-circuit  
protection, output over-voltage protection and thermal  
shutdown.  
● Thermal Shutdown  
● -40℃ to +85℃ Operating Temperature Range  
● Available in Green WLCSP-0.8×1.2-6B and  
TDFN-2×2-6L Packages  
APPLICATIONS  
PMOLED and Sensor Power Supplies  
Wearable Devices  
The SGM6602 is available in Green WLCSP-0.8×1.2-6B  
and TDFN-2×2-6L packages. It operates over an  
ambient temperature range of -40℃ to +85℃.

OVERSTRESS CAUTION  
ABSOLUTE MAXIMUM RATINGS  
Stresses beyond those listed in Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to  
absolute maximum rating conditions for extended periods  
may affect reliability. Functional operation of the device at any  
conditions beyond those indicated in the Recommended  
Operating Conditions section is not implied.

ESD SENSITIVITY CAUTION  
This integrated circuit can be damaged if ESD protections are  
not considered carefully. SGMICRO recommends that all  
integrated circuits be handled with appropriate precautions.  
Failureto observe proper handlingand installation procedures  
can cause damage. ESD damage can range from subtle  
performance degradation tocomplete device failure. Precision  
integrated circuits may be more susceptible to damage  
because even small parametric changes could cause the  
device not to meet the published specifications.
