Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

The FAN6100M is a highly integrated secondary side
constant voltage and constant current controller that
is compatible with MediaTek Pump ExpressTM Plus
and Fairchild’s FCP-Single communication protocol
specifications. It is designed for use in application that
requires Constant Voltage (CV) and Constant Current
(CC) regulation.
The controller consists of two operational amplifiers
for voltage and current loop regulation with adjustable
reference voltage. The CC control loop also
incorporates a current sense amplifier with gain of 10.
Outputs of the CV and CC amplifiers are tied together
in open drain configuration.
The FAN6100M enables power adaptor’s output
voltage adjustment if it detects a protocol capable
powered device. It can be capable of outputting 5 V at
the beginning, and then 7 V, 9 V or 12 V to meet
requirements of a high voltage dedicated charging
port (HVDCP) power supply or 4.8 V, 4.6 V, 4.4 V,
4.2 V or 4 V to maximize the charging current which is
controlled by the power adaptor. If a non compliant
powered device is detected, the controller disables
output voltage adjustment to ensure safe operation
with smart phones and tablets that support only 5 V.
FAN6100M also incorporates an internal charge
pump circuit to maintain CC regulation down to the
power supply’s output voltage, Vbus of 2 V without an
external voltage supply to the IC. Programmable
cable voltage drop compensation allows precise CV
regulation at end of USB cable via adjusting one
external resistor.
The device is available in the 20-pin MLP 3 x 4
package.

owners.

FAN6100M — Secondary-Side CV / CC Controller Compatible with MediaTek Pump ExpressTM Plus
Typical Performance Characteristics
The highly integrated secondary-side power Constant
Voltage and Constant Current Controller FAN6100M is
TM
compatible with MediaTek Pump Express Plus fastcharging
and
Fairchild’s
own
FCP-Single
communication protocol for quick charger applications. It
can be an optimal solution for quick charger
requirement. The FAN6100M enables power supply’s
output voltage adjustment if it detects a protocol capable
mobile phone and/ or tablet. When a compliant powered
device is detected, the FAN6100M will produce BC1.2
procedure then will be ready to acknowledge which
protocol comes in. At that moment Output voltage is
generated to 5 V as default and then changes to 7 V,
9 V or 12 V to meet quick charger requirements of
HVDCP power supplies. These voltages are based on
the capabilities of the downstream device. The
downstream device requests an output voltage for the
HVDCP power supply. If a non compliant powered
device is detected, the controller disables adaptive
output voltage to ensure safe operation with smart
phones and tablets that support only 5 V.
Constant-Voltage Regulation Operation
Figure 35 shows the primary-side internal PWM control
circuit of the FAN501A and secondary side regulator
circuit of the FAN6100M which consists of two
operational amplifiers for constant voltage (CV) and
constant current (CC) regulation with adjustable voltage
references.
The constant voltage (CV) regulation is implemented in
the same way as the conventional isolated power
supply. Output voltage is sensed on the VREF pin via
the resistor divider, RF1 and RF2 and compared with the
internal reference voltage for constant voltage regulation
(VCVR) to generate a CV compensation signal (COMV)
on the SFB pin. The compensation signal is transferred
to the primary-side using an opto-coupler and applied to
the PWM comparator through attenuator Av to
determine the duty cycle.
Constant-Current Regulation Operation
The constant current (CC) regulation is implemented
with sensing the output current. The output current is
sensed via the current-sense resistor (RCS) connected
between the CSP and CSN pins and placed on the
output ground return path. The sensed signal is
amplified by internal current sensing amplifier AV-CCR
before the amplified current feedback signal is fed into
the positive terminal of the internal operational amplifier
and compared with the internal reference voltage for
constant current regulation (VCCR) to generate a CC
compensation signal (COMI) on the SFB pin. The
compensation signal is transferred to the primary-side
using an opto-coupler to the primary-side PWM
controller.
The controller consists of two operational amplifiers for
constant voltage (CV) and constant current (CC)
regulation with adjustable references voltage. The CC
control loop also incorporates a current sense amplifier
with a gain of 10. Outputs of the CV and CC amplifiers
are tied together in open drain configuration. FAN6100M
also incorporates an internal charge pump circuit to
maintain CC regulation down to the power supply’s
output voltage, Vbus of 2 V without an external voltage
supply to the IC. Programmable cable voltage drop
compensation allows precise CV regulation at the end of
USB cable via adjusting one external resistor.
Protection functions of the FAN6100M include adaptive
VIN Over-Voltage Protection (VIN OVP) and adaptive VIN
Under-Voltage Protection (VIN UVP).

VEA is compared with an internal sawtooth waveform
(VSAW ) by PWM comparators to determine the duty
cycle. As seen in Figure 35, output of the comparator is
used as a reset signal of flip-flop to determine the
MOSFET turn-off instant. The lower signal, either
COMV or COMI, is transferred to the primary-side to
determine the duty cycle, as shown in Figure 36. During
CV regulation, COMV is transferred to the primary-side
to determine the duty cycle while COMI is saturated to
HIGH. During CC regulation, COMI is transferred to the
primary-side to determine the duty cycle while COMV is
saturated to HIGH.

For HVDCP power supply applications, a discharge path
on the output of the HVDCP power supply is necessary
to ensure that a high output voltage level can transfer to
a low output voltage level quickly during mode changes.
This is especially critical under no-load condition where
the natural decay rate of the output voltage is low. To

from high output voltage to low output voltage can

Figure 38 shows the supply voltage circuit, including VDD

directly to the output terminal of a power supply.
During startup, the charge-pump circuit is enabled when
VIN voltage is larger than 2 V and disabled after 40 ms from
the VDD voltage reaches VDD-ON (3.65 V). The charge-pump
circuit is used to boost the VDD voltage to maintain normal
operation for the controller when output voltage is low. The
charge-pump stage includes a low dropout (LDO) preregulator and a charge-pump circuit. The LDO preregulator regulates the input voltage of charge-pump circuit
to 2.7 V and then boosts up the VDD voltage when VIN is
lower than VIN-CP (6.4 V) and out of Green Mode. When VIN
is greater than the value 6.2 V which subtract VIN-CP from
VIN-CP-Hys or lower than VIN-CP (6.4 V) in Green Mode, the
charge-pump circuit is disabled and the VIN voltage is fed
directly to VDD.
