AP1609
PWM/PFM DUAL MODE STEP-UP DC/DC CONVERTER
General Description
Features
The AP1609 is a high efficient step-up DC/DC converter. Large
output current is possible having a built in internal N channel
MOSFET, and using an external coil and diode.

Input Voltage Range: 2.5~6V
Output Voltage Range: 3.0~17V (±2.5%)
PWM/PFM Switching Control
Oscillator Frequency: 300KHz (±20%)
High Efficiency: 91% (Typ.)
Stand-by Current: ISTB 1 = µA (Typ.)
Built-in internal N-Channel MOS
Lead-Free and Green Package: SOP-8L
Lead Free Finish/RoHS Compliant for Lead Free
products (Note 1)
Output voltage is programmable with 1.23V of standard voltage
supply internal, and using externally connected components,
output voltage (FB) can be set up at will.
With a 300KHz switching frequency, the size of the external
components can be reduced. Control switches from PFM to PWM
during light loads with the AP1609 (PWM/PFM switchable) and
the series are highly efficient from light loads to large output
currents.
During stand-by time (CE pin “Low”), current consumption is
reduced to 1µA.
