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 Package: SOP-8L
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.
SOP-8L: Available in “Green” Molding Compound
(No Br, Sb)
Lead Free Finish/ RoHS Compliant (Note 1)
•
During stand-by time (CE pin “Low”), current consumption is
reduced to 1µA.
