DESCRIPTION
FEATURES
The A7506 is synchronous, fixed frequency, step-up
DC/DC converters delivering high efficiency in a
6-lead SOT package. Capable of supplying 3.3V at
100mA from a single AA cell input, the device
contain an internal NMOS switch and PMOS
synchronous rectifier. A switching frequency of
1.2MHz minimizes solution footprint by allowing the
use of tiny, low profile inductors and ceramic
capacitors. The current mode PWM design is
internally compensated, reducing external parts
count. The A7506 features continuous switching at
light loads. Anti-ringing control circuitry reduces EMI
concerns by damping the inductor in discontinuous
mode, and the device features low shutdown current
of under 1µA.
The A7506 is available in SOT-26 Package.
High Efficiency: Up to 92%
