AP1609SL-13

PART OBSOLETE - USE PAM2423 AP1609 PWM/PFM DUAL MODE STEP-UP DC/DC CONVERTER General Description Features OBSOLETE – PART DISCONTINUED 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 SOP-8L: Available in “Green” Molding Compound (No Br, Sb) Lead Free Finish/ RoHS Compliant (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.
