Product Brief  
AS1329  
Low Voltage, Micropower, DC-DC Step-Up Converters  
1 General Description  
2 Key Features  
95% Efficiency  
The AS1329A, AS1329B and the AS1329C are synchro-  
nous, fixed frequency, very high-efficiency DC-DC boost  
converters capable of supplying 3.3V at 160mA from a  
single AA-supply. Compact size and minimum external  
parts requirements make these devices perfect for mod-  
ern portable devices.  
Single-Cell Operation  
Delivers 160mA @ 3.3V (from Single AA Cell)  
Delivers 220mA @ 5.0V (from Two AA Cells)  
Delivers 570mA @ 3.3V (from Two AA Cells)  
Low Start-Up Voltage: 0.85V  
High-speed switching frequency (1.2MHz) and internally  
compensated PWM current mode design provide highly-  
reliable DC-DC conversion, especially when driving  
white LEDs.  
High-Speed Fixed-Frequency: 1.2MHz  
Internal PMOS Synchronous Rectifier  
Automatic Powersave Operation (AS1329A&B)  
Continuous Switching at Light Loads (AS1329C)  
Anti-Ringing Control Minimizes EMI  
Logic Controlled Shutdown (< 1µA)  
Output Range: 2.5 to 5.0V  
The converters are available as the standard products  
listed in Table 1.

AS1329C Continuous Switching  
The devices contain two internal MOSFET switches:  
one NMOS switch and one PMOS synchronous rectifier.  
6-pin TSOT-23 Package  
Anti-ringing control circuitry reduces EMI by damping  
the inductor in discontinuous mode, and the devices  
exhibit extremely low quiescent current (< 1µA) in shut-  
down.  
3 Applications  
The AS1329 is ideal for low-power applications where  
ultra-small size is critical as in medical diagnostic equip-  
ment, hand-held instruments, pagers, digital cameras,  
remote wireless transmitters, MP3 players, LCD bias  
supplies, cordless phones, GPS receivers, and PC  
cards.  
In shutdown mode the battery is connected directly to  
the output enabling the supply of real-time-clocks.  
The AS1329 is available in a 6-pin TSOT-23 package.
