MCP1663 DEVICE OVERVIEW
The MCP1663 is a compact, high-efficiency, fixed-frequency, non-synchronous step-up
DC/DC converter which integrates a 36V, 400 m switch. This product provides a
space-efficient high voltage step-up, easy-to-use power supply solution. The MCP1663
was developed for applications powered by two-cell or three-cell alkaline, Energizer®
Lithium Primary, Ni-Cd, Ni-MH batteries, or Li-Ion or Li-Polymer batteries.
The MCP1663 operates in Pulse-Width Modulation (PWM), at a fixed 500 kHz
switching frequency. The device features an under-voltage lockout (UVLO) which
prevents fault operation below 1.85V (UVLOSTOP) corresponding to the value of two
discharged batteries. The MCP1663 starts its normal operation at 2.3V input voltage
(UVLOSTART) and the operating input voltage ranges from 2.4V to 5.5V.
For standby applications, MCP1663 can be put in Shutdown by pulling the EN pin to
GND. The device will stop switching and will consume a few µA of input current
(including feedback divider current; the device consumes 300 nA typical). In the Boost
configuration, the input voltage will be bypassed to output through the inductor and
Schottky diode.
MCP1663 also provides over-voltage protection (OVP) in the event of:
• Short-circuit of the feedback pin to GND
• Disconnected feedback divider
In these conditions, the OVP function will stop the internal driver and prevent damage
to the device. This feature is disabled during the start-up sequence and Thermal
Shutdown state.
The goal of the MCP1663 9V/12V/24V Output Boost Regulator Evaluation Board is to
demonstrate the higher output voltage and output current capabilities of the MCP1663
Boost Converter.

HIGH INPUT VOLTAGE CONFIGURATION
The MCP1663 9V/12V/24V Output Boost Regulator Evaluation Board comes with two
additional configurations that can be used to extend and overcome the typical low VIN
voltage range, providing significantly more flexibility for applications powered from a
higher input. The MCP1663 high-input voltage boost converter (the bottom circuit on
the evaluation board) comes with two different solutions that can be used to extend the
application's input voltage range beyond its typical values. For this circuit, VIN
represents the voltage applied between the VIN and GND test points on the board and
VDD represents the voltage that will be present on the MCP1663 input pin.
• The first option used for driving the MCP1663’s low input (VDD) voltage internal
circuitry is to use a linear dropout regulator (LDO) to step-down the application
supply voltage (VIN) to 5V.
• The second solution to limit the VIN voltage is to use a Zener diode regulator.
The MCP1663 low input quiescent current keeps the LDO and the Zener diode circuitry
power losses at a low level.

WHAT IS THE MCP1663 9V/12V/24V OUTPUT BOOST REGULATOR
EVALUATION BOARD?
The MCP1663 9V/12V/24V Output Boost Regulator Evaluation Board is used to
evaluate and demonstrate Microchip Technology’s MCP1663 Switching Boost
Regulator. This board demonstrates the MCP1663 capabilities in two different
applications:
• 9V or 12V selectable output Boost Converter application supplied from an
external voltage source (VIN < 5.5V e.g. Li-Ion cell boost to 9V or 12V). This
typical step-up configuration is meant to highlight the MCP1663 basic boost
operation.
• 24V Output Boost converter application supplied from high voltage input rail (e.g.
9V - 16V). This application provides solutions for the particular situation in which
the required input voltage is outside the typical operating range (e.g. VIN = 12V
boost to 24V Output). J1 jumper is used to choose between stepping down the VIN
voltage using the LDO or the Zener diode circuitry.
The board can be used to evaluate the SOT-23-5 lead package. The MCP1663
9V/12V/24V Output Boost Regulator Evaluation Board was developed to help
engineers reduce product design cycle time.
The output voltage is set to the proper value using an external resistor divider, resulting
in a simple and compact solution.

Chapter 2. Installation and Operation
2.1
INTRODUCTION
MCP1663 is a non-synchronous, fixed-frequency step-up DC/DC converter which has
been developed for applications that require higher output voltage capabilities.
MCP1663 can regulate the output voltage up to 32V and can deliver up to 250 mA load
at 3.3V input and 12V output (see Figure 2-3). At light loads, MCP1663 skips pulses to
keep the output ripple low. The regulated output voltage (VOUT) should be greater than
the input voltage (VIN).
Another important feature is that the device integrates the compensation and protection
circuitry, such that the final solution lowers total system cost, eases implementation and
requires a minimum number of additional components and board area.
2.1.1

2.2
GETTING STARTED
The MCP1663 9V/12V/24V Output Boost Regulator Evaluation Board is fully
assembled and tested to evaluate and demonstrate the MCP1663 product. This board
requires the use of external laboratory supplies and load.
2.2.1
Power Input and Output Connection
2.2.1.1
POWERING THE MCP1663 9V/12V/24V OUTPUT BOOST REGULATOR
EVALUATION BOARD
The MCP1663 9V/12V/24V Output Boost Regulator Evaluation Board was designed
to be used to evaluate the MCP1663 device. The package selected is SOT-23.
Soldered test points are available for input voltage connections.
Soldered test points are available to connect a load. The switch peak current limit will
provide a safe maximum current value. The maximum output current for the converter
will vary with input and output voltages; refer to Figure 2-3 or the MCP1663 data sheet
for more information on the maximum output current.
2.2.1.2
BOARD POWER-UP PROCEDURE
TOP CIRCUIT
1. Connect the input supply as shown in Figure 2-2. The input voltage should not
be higher than 5.5V.
2. Connect system load to VOUT and GND terminals; maximum load varies with
input and output voltage. Connect the (+) side of the load to VOUT and the
negative (-) load to ground (GND).
3. The “VOUT SELECT” switch can be used to modify the output voltage between
two values:
- 9V, when the switch is in OFF position
- 12V, when the switch is in ON position
BOTTOM CIRCUIT
1. Connect the input supply as shown in Figure 2-2.
2. The MCP1663 can be used in the extended input voltage range 9V - 16V.
3. Connect system load to VOUT and GND terminals; maximum load varies with
input and output voltage. Typically, the MCP1663 can supply a 24V output with
500 mA from a 12V input source at room temperature. Connect the (+) side of
the load to VOUT and the negative (-) load to ground (GND).
4. There are two distinct methods that can be used to extend the input voltage
range:
- Using an LDO to provide the necessary low voltage (VDD) bias (jumper on J1
in “LDO” position)
- Using a Zener diode (jumper on J1 in “Zener” position)

2.2.1.3
ADJUSTABLE VOUT SETTING
The top circuit comes with the output value set to 9V and 12V (VOUT selective using a
switch). If a different output is desired, set the switch in the OFF state (button down)
and recalculate the resistor divider (RT1 and RB1) using Equation 2-1.
The Bottom circuit comes with VOUT set to 24V. As in the previous case, the same
equation can be used to calculate RT and RB and set another output voltage. Note that
VIN must be lower than VOUT.

BATTERY CONSIDERATIONS
When considering a power solution for a design, the battery needs to be carefully
selected. Alkaline batteries are a commonly available option that delivers good
performance in a variety of applications. Energizer® Ultimate Lithium batteries are an
alternative power solution that provide superior-performance high drains and allows
designers to utilize the full power range of the MCP1663 without sacrificing size or
runtime.
Energizer Ultimate Lithium batteries utilize a primary cell chemistry that contain higher
energy than alkaline batteries, and have much better high drain performance. Ultimate
Lithium batteries produce a high, flat voltage profile that enables them to provide a high
energy capacity even at high drains. Additionally, Ultimate Lithium batteries have a very
low internal resistance, allowing them to maintain a high voltage at very high loads.
