DUAL OUTPUT BOOST REGULATOR USING SINGLE INDUCTOR
2.5-V to 6-V Input Voltage Range
The TPS61140/1 is a dual output boost converter IC.
It is intended to be configured as a highly integrated
Two Outputs Each up to 27 V
power solution providing regulated voltage and
0.7-A Integrated Switch
current output with one boost converter. This device
Built-In Power Diode
is ideal for driving the OLED sub display and WLED
1.2-MHz PWM for WLED Driver
backlight for the LCD main display in clam shell
phones. The voltage and current can be individually

programmed through external resistors. There is a

dedicated selection pin for each output, so the two

or
simultaneously. When only the voltage output is

efficiency over a wide load range. If the current
output is selected, the device adopts a 1.2-MHz
Up to 82% Efficiency
pulse width modulation control (PWM) method in
Up to 30 kHz PWM Dimming Frequency
order to maximize output current. Applying an

external PWM signal to the select pin (SELI) reduces
the output current thereby allowing WLED dimming.
The TPS61140/1 has a built-in power MOSFET and
Clamshell Phone With OLED/LCD Screen
power diode; thereby, eliminating the needs for any
external active power components. In addition, the
high
switching
frequency
reduces
the
external
inductor and capacitor sizes. Overall, the IC provides
a highly compact solution with high efficiency and
plenty of flexibility.
