Texas Instruments TPS65132A0YFFR

Overview

TPS65132A0YFFR from Texas Instruments is a single-inductor, dual-output power supply IC designed for bipolar LCD display bias rails. It delivers +5.0 V / 40 mA and –5.0 V / 40 mA from a 2.5 V–5.5 V input, uses I²C programmability for sequencing and voltage selection, and integrates a synchronous boost converter with LDO and negative charge pump in a 15-ball DSBGA (2.11 mm × 1.51 mm) package - deployed in smartphone and tablet display power systems.

For engineers reviewing the TPS65132A0YFFR datasheet, TPS65132A0YFFR pinout, TPS65132A0YFFR application, or TPS65132A0YFFR equivalent, key selection criteria include its pre-programmed ±5.0 V outputs, 40 mA per rail current capability, I²C-configurable power-up/down sequencing, active discharge control, and compact CSP footprint optimized for space-constrained portable displays.

Technical Context

The TPS65132A0YFFR implements a single-inductor topology where a synchronous boost converter generates an intermediate regulated voltage (REG), which feeds both a low-dropout linear regulator (LDO) for VPOS and a negative charge pump (CPN) for VNEG. Its I²C interface enables dynamic configuration of output voltages, sequencing order, and active discharge behavior - critical for managing display driver startup transients and ESD-safe shutdown.

It operates across –40°C to +85°C ambient, supports standard- and fast-mode I²C (100 kHz / 400 kHz), features undervoltage lockout (UVLO) with 2.5 V rising threshold and 40 ms delay for noise immunity, and delivers >85% efficiency at >10 mA load and >90% at >40 mA - achieved via PFM/CCM mode switching and internal compensation.

FAQ

What output voltages does the TPS65132A0YFFR provide?

The TPS65132A0YFFR is factory-programmed to deliver +5.0 V on the OUTP pin and –5.0 V on the OUTN pin, each with ±1% accuracy over –40°C to +85°C ambient temperature. These values are fixed and cannot be altered via I²C; they match common display driver IC requirements for medium-size LCD and AMOLED panels.

Does the TPS65132A0YFFR require external inductors or capacitors?

Yes, the TPS65132A0YFFR requires an external 4.7 µH inductor between VIN and SW, two 2.2 µF X7R flying capacitors (CFLY1/CFLY2), one 4.7 µF input capacitor (CIN), and two 4.7 µF output capacitors (COUTP/COUTN). The REG pin also needs a 4.7 µF capacitor. All are specified in the TI datasheet Section 7.3.

How does the TPS65132A0YFFR handle power sequencing between VPOS and VNEG?

The TPS65132A0YFFR supports I²C-programmable sequencing via ENP and ENN pins. By default, it enables VPOS first, then VNEG, with configurable delays. Sequencing can be modified through register writes to meet specific display driver startup timing requirements - preventing latch-up or visual artifacts during panel initialization.

What is the maximum continuous output current per rail for the TPS65132A0YFFR?

The TPS65132A0YFFR delivers up to 40 mA continuously on both VPOS and VNEG rails under typical conditions (T_A ≤ 85°C, proper PCB thermal design). It is rated for 80 mA peak per rail in pulsed operation, but sustained 40 mA is the guaranteed specification for stable operation in the 15-ball DSBGA package.

Is the TPS65132A0YFFR pin-compatible with other variants in the TPS65132 family?

Yes, all TPS65132x YFFR variants - including TPS65132A0YFFR, TPS65132AYFFR, and TPS65132B0YFFR - share identical 15-ball DSBGA (YFF) packaging, pin assignment, and mechanical footprint. This allows direct substitution in existing layouts when changing pre-programmed output voltages or discharge characteristics.
