1 General Description
The AS1335 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 400µA and
decreases to
≤1µA
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.

How to get CPU external frequency under DOS?
I don't see any method to get the external frequency in the CPUID instruction, but the main frequency can be obtained through RDTSC. Is there any way to get the external frequency? ? ? Thank you...
