توضیحات
The MP3398A is a step-up controller with 4
current channels, which is designed to drive
WLED arrays for large-size LCD-panel
backlighting applications. It is flexible to expand
the number of LED channels by two or more
ICs in parallel sharing a single inductive power
source.
The MP3398A uses peak-current mode with
fixed switching frequency. The frequency is
programmable by an external setting resistor.
The MP3398A drives an external MOSFET to
boost up the output voltage from a 5V to 28V
input supply. It regulates the current in each
LED string to the value set by an external
current-setting resistor.
The MP3398A applies 4 internal current
sources for current balance. The current
matching can achieve 2.5% regulation accuracy
between strings. Its low regulation voltage on
LED current sources reduces power loss.
The MP3398A can support both analog and
PWM dimming independently to meet the
different dimming-mode request. In addition,
rich protection modes are also integrated
including OCP, OTP, UVP, OVP, LED
short/open protection, inductor/diode short
protection.
The MP3398A is available in SOIC16,
TSSOP16-EP and SOIC20 packages.
