. This causes a known increase in full-
scale charging current (PWM = 0) of 3% due to the 5k input
resistance of the I
FB
pin. Note that 100% duty cycle gives full
charging current and that very low duty cycles (especially
zero!) will not operate correctly. Very low duty cycle (<10%)
is a problem because the peak detector requires a finite
up-time to reset C6.

More Help
Linear Technology Field Application Engineers have a CAD
spreadsheet program for detailed calculations of circuit
operating conditions, and our Applications Department is
always ready to lend a helping hand. For additional informa-
tion refer to the LT1372 data sheet. This part is identical to
the LT1512 except for the current amplifier circuitry.
