is a high-efficiency, constant-frequency synchronous buck converter available in a fixed or an adjustable output voltage version. The wide input volt- age range 2.6V
to 5.25V), the high output current (up to 1.5A) and minimal external component requirements make the AS1335
perfect for any single Li-Ion battery- powered application. Typical supply current with no load is 400?A and decreases to ?1?A in shutdown mode. The highly effi- cient duty cycle (100%) provides low dropout operation, prolonging Battery
life in portable systems. The device also offers a power-ok signal with a 215ms delay, which can be reseted or delayed further via the RSI pin. 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. The AS1335
is available in a 10-pin TDFN 3x3mm pack- age.
