Description  
frequency (I > 10 mA)  
O
The STOD02 is a dual DC-DC converter meant to  
power AMOLED displays. It integrates a step up  
and an inverting DC-DC converter making it  
particularly suitable for battery operated products,  
where the major concern is the overall system  
efficiency. STOD02 works in pulse skipping mode  
during low load condition and in PWM-mode (at  
1.6 MHz) for medium/high load condition. The  
high frequency allows reducing the value and  
number of external components just to 6  
components needed. The enable pin allows  
turning off the device so reducing the current  
consumption to less that 1 µA. The negative  
output voltage can be programmed by an MCU  
through a dedicated pin which implements single-  
wire protocol. Soft-start with controlled inrush  
current limit and thermal shutdown are integrated  
functions of the device.  
Enable pin for shutdown mode  
Low quiescent current: < 1 µA in shutdown  
mode  
Soft-start with inrush current protection  
Over temperature protection  
Temperature range: -40 °C to 85 °C  
True shutdown mode  
Fast outputs discharge circuit after shutdown  
Package: DFN 12 leads - (3 x 3 mm)
