What are the key features of TPS61132PWG4?
- Dual-channel step-down/up (buck-boost) topology covering 1.8 V to 6.5 V input for seamless single-cell Li-Ion or 3 V to 6 V adapter operation
- Current-mode PWM control with fast transient response for stable output regulation under rapidly changing LED backlight or display panel loads
- 16-pin TSSOP package enabling compact PCB layout suitable for TFT LCD bias supply and OLED panel power rails in slim portable devices
What is TPS61132PWG4 used for?
The TPS61132PWG4 is primarily used as a dual-rail power supply for TFT LCD displays and OLED panels in smartphones, tablets, and portable navigation devices that require positive and negative gate voltages generated from a single Li-Ion cell. Its 1.8 V to 6.5 V input range ensures continuous output regulation as the battery discharges from 4.2 V to 2.7 V without requiring a separate pre-regulator. The compact TSSOP-16 footprint and integrated current-mode control minimise the external inductor and capacitor count, reducing total BOM area in slim handheld consumer electronics.

Frequently Asked Questions
What input voltage range does TPS61132PWG4 support, and can it be powered directly from a single Li-Ion cell?
The TPS61132PWG4 accepts an input voltage from 1.8 V to 6.5 V, covering the full discharge curve of a single Li-Ion cell from 4.2 V down to approximately 2.7 V, as well as 3.3 V regulated rails and USB 5 V supplies, making it versatile for battery-powered portable devices without an additional pre-regulator stage.
Why is a buck-boost topology important for TFT LCD bias supply designs using TPS61132PWG4?
TFT LCD panels require both a positive supply (typically +5 V) and a negative supply (typically -5 V) that may be above or below the Li-Ion battery voltage at various states of charge. The step-down/up topology in TPS61132PWG4 maintains regulated dual-rail outputs across the full 1.8 V to 6.5 V input range without output dropout, ensuring stable display contrast and gate-driver timing throughout the battery discharge cycle.
How does current-mode PWM control in TPS61132PWG4 benefit dynamic load applications like display backlights?
Current-mode PWM control inherently limits inductor peak current on a cycle-by-cycle basis, providing fast transient response when the PWM dimming signal switches the LED backlight load rapidly between zero and full current. This prevents output voltage overshoot that could damage display panel gate drivers and reduces output capacitor requirements, saving PCB space in slim devices.
Can TPS61132PWG4 also operate at 3.3 V input for designs powered from a regulated system rail?
Yes, TPS61132PWG4 is confirmed to operate at 3.3 V input, which is within its specified 1.8 V to 6.5 V input range. This allows direct connection to a system 3.3 V bus in tablets and embedded display boards, generating the higher positive and negative LCD bias voltages needed from a single TSSOP-16 converter without an intermediate voltage rail.
