500kHz, 36V Output, 600mW PWM Step-Up DC-DC Converter
General Description
The MAX15032 constant-frequency, pulse-width-modu-
lating (PWM), low-noise boost converter is intended for
low-voltage systems that need a locally generated high
voltage. This device is capable of generating low-noise,
high output voltages, with an output power capability
up to 600mW with a 2.9V input voltage. This device can
be used for a wide variety of applications, such as PIN
or varactor diode biasing and LCD displays. The
MAX15032 operates from +2.7V to +11V.
The constant-frequency (500kHz), current-mode PWM
architecture provides low-noise output voltage that is
easy to filter. A high-voltage internal lateral DMOS
power switch allows this device to boost output volt-
ages up to 36V. The MAX15032 features a shutdown
mode to save power.
The MAX15032 is available in a small thermally
enhanced 3mm x 3mm 8-pin TDFN package and is
specified for operation over the -40°C to +125°C auto-
motive temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1:Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to /thermal-tutorial.

Pin Description
PINNAMEFUNCTION
1LXDrain of Internal 40V n-Channel DMOS. Connect inductor/diode to LX. Minimize trace area at LX to
reduce switching noise emission.GNDSignal Ground. Connect directly to the local ground plane. Connect GND to PGND at a single point,
typically near the output capacitor return terminal.
3FBFeedback Regulation Point. Connect to the center tap of a resistive divider from the output (VOUT) to
GND to set the output voltage. The FB voltage regulates to 1.245V (typ).SHDN
Active-Low Shutdown Control Input. A logic-low voltage on SHDN shuts down the device and reduces
the supply current to 0.5µA (max). Connect SHDN to IN for always-on operation. Do not connect
SHDN to a voltage higher than VIN.INInput Supply Voltage. Bypass IN to PGND with a 4.7µF minimum ceramic capacitor.
6CNNegative Terminal of the Charge-Pump Flying Capacitor for 2.7V to 5.5V Supply Voltage Operation.
Leave CN unconnected when the input voltage is in the +5.5V to +11V range.
7CPPositive Terminal of the Charge-Pump Flying Capacitor for 2.7V to 5.5V Supply Voltage Operation.
Connect to IN when the input voltage is in the +5.5V to +11V range.PGNDPower Ground. Connect the input and output filter capacitors’ negative terminal to PGND. Connect
externally to GND at a single point, typically at the output capacitor return terminal.
—EPExposed Pad. Connect EP to a large copper plane at the GND potential to improve thermal
dissipation. Do not use as the main GND connection.
