GENERAL DESCRIPTION  
The ADP2126/ADP2127 are high frequency, step-down, dc-to-  
dc converters optimized for portable applications in which board  
area and battery life are critical constraints. The fixed 6 MHz  
operating frequency enables the use of tiny ceramic inductors  
and capacitors and the regulators use spread spectrum frequency  
modulation to reduce EMI. Additionally, synchronous rectification  
improves efficiency and results in fewer external components.  
The ADP2126/ADP2127 are enabled by a 6 MHz to 27 MHz  
external clock signal applied to the EXTCLK pin. Certain models  
can also be enabled with a logic high signal. When the external clock  
is not switching and in a low logic state, the ADP2126/ADP2127  
stop regulating and shut down to draw less than 0.3 μA (typical)  
from the source.  
The ADP2126/ADP2127 have an input voltage range of 2.1 V to  
5.5 V, allowing the use of single Li+/Li polymer cell, three-cell  
alkaline, NiMH cell, and other standard power sources. The  
ADP2126/ADP2127 are internally compensated to minimize  
external components and can source up to 500 mA. Other key  
features, such as cycle-by-cycle peak current limit, soft start,  
undervoltage lockout (UVLO), output-to-ground short-circuit  
protection, and thermal shutdown provide protection for internal  
and external circuit components.  
At high load currents, the ADP2126/ADP2127 use a voltage  
regulating pulse-width modulation (PWM) mode that maintains  
a constant frequency with excellent stability and transient response.  
Light load operation is determined by the state of the MODE pin.  
In forced PWM mode, the converter continues operating in PWM  
for light loads. Under light load conditions in auto mode, the  
ADP2126/ADP2127 automatically enter a power-saving mode,  
which uses pulse frequency modulation (PFM) to reduce the  
effective switching frequency, thus ensuring the longest battery  
life in portable applications.
