NOTE: THIS CIRCUIT CAN OPERATE WITH AUX1, AUX2, OR AUX3 ON THE MAX1566,
AND WITH AUX1 OR AUX3 ON THE MAX1567. TO USE AUX3, FB3L = GND,
AND FB3H IS USED FOR FEEDBACK.

Figure 11. ±15V Output Using an AUX-Driven Boost with
Charge-Pump Inversion
SDOK pulls low when the step-down has successfully
completed soft-start. SDOK goes high impedance in
shutdown, overload, and thermal limit. A typical use for
SDOK is to drive a P-channel MOSFET that connects
3.3V power to the CPU I/O after the CPU core is pow-
ered up (Figure 15), thus providing safe sequencing in
hardware without system intervention.
A U X 1 O K pulls low when the AUX1 controller has suc-
cessfully completed soft-start. AUX1OK goes high
impedance in shutdown, overload, and thermal limit. A
typical use for AUX1OK is to drive a P-channel MOSFET

output linear regulator (MAX1616) can be used to regulate the
negative output of the charge pump.)
that connects 5V power to the CCD after the 15V CCD
bias (generated by AUX1) is powered up (Figure 16).
SCF goes high (high impedance, open drain) when
overload protection occurs. Under normal operation,
SCF pulls low. SCF can drive a high-side P-channel
MOSFET switch that can disconnect a load during
power-up or when a channel turns off in response to a
logic command or an overload. Several connections
are possible for SCF. One is shown in Figure 17 where
SCF provides load disconnect for the step-up on fault
and power-up.
