5 M H z , 6 0 0 m A , D C / D C St e p - D o w n R e g u l a t o r D a ta S he e t 1 General Description The AS1324 is a high-efficiency, constant-frequency synchronous buck converter available in adjustable- and fixed-voltage versions.
The wide input voltage range (2.
7V to 5.
5V), automatic powersave mode and minimal external component requirements make the AS1324 perfect for any single Li-Ion battery-powered application.
Typical supply current with no load is 30µA and decreases to ≤1µA in shutdown mode.
The AS1324 is available as the standard versions listed in Table 1.

8V 2 Key Features ! ! ! ! ! ! ! ! ! ! ! ! High Efficiency: Up to 96% Output Current: 600mA Input Voltage Range: 2.
7V to 5.
5V Constant Frequency Operation: 1.
5MHz Variable- and Fixed-Output Voltages No Schottky Diode Required Automatic Powersave Operation Low Quiescent Current: 30µA Internal Reference: 0.
6V Shutdown Mode Supply Current: ≤1µA Thermal Protection 5-pin TSOT-23 Package An internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode.
The internally fixed switching frequency (1.
5MHz) allows for the use of small surface mount external components.
Very low output voltages can be delivered with the internal 0.
6V feedback reference voltage.
The AS1324 is available in a 5-pin TSOT-23 package.
3 Applications The device is ideal for mobile communication devices, laptops and PDAs, ultra-low-power systems, threshold detectors/discriminators, telemetry and remote systems, medical instruments, or any other space-limited application with low power-consumption requirements.
