AP1621  
PWM/PFM Dual Mode Step-down DC/DC Controller  
„ Features  
„ General Descriptions  
The AP1621 series are multi-functional step-down  
DC/DC converters with built-in speed, low ON  
resistance drivers. A more than 1A output current is  
possible using an externally connected transistor,  
coil, diode and capacitor.  
- Input voltage range:2.2V~8VVOUT type)  
- Adjustable version(±2.5%)  
- Oscillator frequency: 270KHz(±15%)  
- High Efficiency: 92%typ .)  
- Stand-by capability: ISTB2µA.max .)  
- Soft-start time set-up externally type possible  
- Output voltage type possibleFB)  
- Package: SOT23-5  
Output voltage is set-up by external resistor. ±2.5%  
accuracy.  
With a 270KHz switching frequency, the size of the  
external components can be reduced.  
Control switches from PWM to PFM during light  
loads with the AP1621PWM/PFM switchableand  
the series is highly efficient from light loads to large  
output currents.  
„ Applications  
Electronic Information Organizers  
Palmtops  
In relation to soft-start time external capacitor  
regulated types.  
Cellular and portable phones  
Portable Audio Systems  
Various Multi-function Power Supplies  
During stand-by time CE pin “LOW”,current  
consumption is reduced to less than 0.5µA.  
With U.V.L.O internal, the external MOSFET. Will  
be forcibly switched off if used below the stipulated  
voltage.
