High-Performance, Step-Up, DC-DC Converter
General Description
The MAX17112 is a high-performance, step-up, DC-DC
converter that provides a regulated supply voltage for
active-matrix thin-film transistor (TFT) liquid-crystal dis-
plays (LCDs). The MAX17112 incorporates current-
mode, fixed-frequency (1MHz), pulse-width modulation
(PWM) circuitry with a built-in, n-channel power MOSFET
to achieve high efficiency and fast-transient response.
The input overvoltage protection (OVP) function pre-
vents damage to the MAX17112 from an input surge
voltage (up to 24V).
The high switching frequency (1MHz) allows the use of
ultra-small inductors and low-ESR ceramic capacitors.
The current-mode architecture provides fast-transient
response to pulsed loads. A compensation pin (COMP)
gives users flexibility in adjusting loop dynamics. The
internal MOSFET can generate output voltages up to
20V from an input voltage between 2.6V and 5.5V.
Features
o Input Overvoltage Protection
o Adjustable Output from V IN to 20V
o 2.6V to 5.5V Input Supply Range
o Input Supply Undervoltage Lockout
o 1MHz Fixed Switching Frequency
o Programmable Soft-Start
o Small 10-Pin, TDFN Package
o Thermal-Overload Protection
Ordering Information
Soft-start slowly ramps the input current and is pro-
grammable with an external capacitor. The MAX17112
is available in a 10-pin TDFN package.
