Typ Output Resistance for C1 = C2 = 100碌F
Selectable Oscillator Frequency: 5kHz/50kHz
8-pin SOIC package.
General Description
The FAN5660 is a monolithic charge-pump which can
invert, double or split a +1.5V to +5.5V input voltage.
Using only two identical low-cost capacitors, the charge
pump replaces switching regulators, thus eliminating
inductors and their associated cost, size, and EMI. The
device has a greater than 90% ef鏗乧iency over most of its load
current range and a typical operating current of only 160碌A(chǔ).
The FAN5660 is ideal for both battery-powered and board-
level voltage conversion applications.
In order to enable the user optimize capacitor size and
quiescent current, the FAN5660 is offered with a frequency
control (FC) pin which selects either 5kHz or 50kHz
operation.
The Oscillator frequency can also be driven with an external
clock. The FAN5660 is available in 8-pin small-outline
packages.
