AS1324 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 (2.7 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 30A and decreases to 1A in shutdown mode. The highly efficient duty cycle (100%) provides low dropout operation, prolonging battery life in portable systems.
The AS1324 is available as the standard versions listed:
| Model | Output Voltage |
| AS1324-AD | Adustable via External Resistors |
| AS1324-12 | Fixed: 1.2V |
| AS1324-15 | Fixed: 1.5V |
| AS1324-18 | Fixed: 1.8V |
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.

AS1341 General Description
The AS1341 is a high-efficiency step-down converter with adjustable output voltages from 1.25V to VIN using supply voltages of up to 20V.
An integrated current-limited 0.4 MOSFET delivers load currents up to 600mA.
The AS1341 also includes a 100% duty cycle LDO mode with a low dropout of only 250mV for high efficiency if input voltages is in the range of the output voltage.
The AS1341 has a low quiescent current (12A) to improve light-load efficiency and minimize battery use, and draws only 0.8A in shutdown mode.
High switching frequencies (up to 200kHz) allow the use of small surface-mount inductors and output capacitors.
The device is available in a TDFN-8 3x3mm pin package.
