A7206
DUAL CHANNEL 1.5MHz, 600mA EACH CHANNEL
SYNCHRONOUS STEP-DOWN DC-DC CONVERTER
DESCRIPTION
FEATURES
A7206 is a dual channel high efficiency monolithic High Efficiency: Up to 96%
synchronous step down current mode DC-DC 600mA Output Current at Vin=3.0V
converter operating at 1.5MHz constant frequency. 1.5MHz Constant Frequency Operation
The device integrates a main switch and a Very Low Quiescent Current of 40uA
synchronous rectifier for high efficiency without an No Schottky Diode Required
external Schottky diode for each of the channels. Low RDS(on) Internal Switches: 0.35Ω
The A7206 can operate from a 2.5V to 5.5V input 0.6V reference allows low Output Voltage
voltage and is ideal for powering portable equipment Current Mode Operation for excellent line and
that runs from a single cell lithium-Ion (Li+) battery.
load transient Response
It can supply 600mA output current for each channel Short-Circuit & Thermal Fault Protection
and can also run at 100% duty cycle for low dropout <1µA Shut Down Current
operation, extending battery life in portable system. Power-On Reset Output
Externally Synchronizable Oscillator
User can select between idle mode or power saving Available in DFN10 package.
mode via Mode/Sync input pin. Idle mode provides
low ripple noise at light load while power saving APPLICATION
Mode provides high efficiency at light load.
