Product details
Overview
TPS65132B2YFFR from Texas Instruments is a single-inductor, dual-output power supply IC designed for bipolar LCD display bias rails. It delivers +5.2 V / 40 mA (VPOS) and –5.2 V / 40 mA (VNEG) from a 2.5 V–5.5 V input, features I²C programmability, >85% efficiency at >10 mA load, and uses a 15-ball DSBGA (YFF) package for space-constrained portable displays.
For engineers reviewing the TPS65132B2YFFR datasheet, TPS65132B2YFFR pinout, TPS65132B2YFFR application, or TPS65132B2YFFR equivalent, this page provides verified electrical parameters, confirmed pin functions, real-world sequencing behavior, I²C register-level control details, and validated alternatives for split-rail display power design.
Technical Context
The TPS65132B2YFFR integrates a synchronous boost converter (1.35–2.25 MHz switching) feeding an LDO for VPOS and a negative charge pump (0.8–1.2 MHz) for VNEG - both sharing one inductor to minimize solution size. Its I²C interface enables dynamic voltage programming, active discharge control, and configurable power-up/down sequencing.
It operates in either continuous conduction mode (CCM) or pulse frequency modulation (PFM) for light-load efficiency, supports 1% output voltage accuracy over –40°C to +85°C, and includes undervoltage lockout (2.3 V falling threshold), thermal shutdown (140°C), and integrated protection for battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 5.5 V - compatible with single-cell Li-ion, Li-polymer, and fixed 3.3 V/5 V rails. |
| VPOS Output | +5.2 V / 40 mA - pre-programmed positive rail; regulated by integrated LDO for low-noise display bias. |
| VNEG Output | –5.2 V / 40 mA - pre-programmed negative rail; generated via inverting charge pump from REG node. |
| Efficiency | >85% at IOUT > 10 mA - enables extended battery life in always-on display segments. |
| Control Interface | I²C (Standard/Fast mode) - allows runtime reconfiguration of voltages, sequencing, and discharge behavior. |
| Package | 15-ball DSBGA (YFF), 2.11 mm × 1.51 mm - ultra-compact footprint for smartphone and wearable PCBs. |
| Quiescent Current | 0.54 mA - low static consumption critical for standby power budgeting in portable devices. |
Pinout & Package
TPS65132B2YFFR uses a 15-ball DSBGA (YFF) package with 0.4-mm pitch and bottom-side solder balls. Thermal performance is optimized via exposed PowerPAD (ball A1) connected to PGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AGND | Analog ground reference | Separate ground for sensitive analog circuitry; must be tied to clean system AGND plane. |
| CFLY1, CFLY2 | Flying capacitor terminals | Connect external 2.2 µF X7R capacitors to enable charge-pump operation for VNEG generation. |
| ENP | VPOS enable input | Active-high digital control for LDO output; used in sequencing to delay VPOS activation. |
| ENN | VNEG enable input | Active-high digital control for charge pump; independent of ENP for asymmetric rail control. |
| OUTP | Positive output terminal | Delivers +5.2 V to display source drivers; requires 4.7 µF ceramic output capacitor. |
| OUTN | Negative output terminal | Delivers –5.2 V to display gate drivers; requires 4.7 µF ceramic output capacitor. |
| PGND | Power ground return | High-current return path for boost switch and charge pump; must be low-inductance connection to VIN GND. |
| REG | Boost converter output | Intermediate rail (~6.2 V typical) feeding both LDO and charge pump; requires 4.7 µF output capacitor. |
| SCL, SDA | I²C bus interface | Supports Standard (100 kHz) and Fast (400 kHz) modes; enables full configuration without external logic. |
| SW | Boost switch node | Connects to external 4.7 µH inductor; high dv/dt node requiring tight layout and guard ring. |
| VIN | Main input supply | Accepts 2.5–5.5 V; feeds all internal blocks; requires 4.7 µF X7R input capacitor near package. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output display power applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65132B0YFFR | Pre-programmed to ±5.0 V; identical pinout, package, and I²C feature set. | Suitable when display panel tolerances allow ±5.0 V instead of ±5.2 V; no layout change required. | Select if system-level testing confirms ±5.0 V meets display IC VDD/VSS specs and reduces margin risk. |
| TPS65132L1YFFR | Pre-programmed to ±5.1 V; same 40 mA output capability and YFF package; slower startup (500 µs). | Better fit for panels requiring tighter mid-range bias voltage; retains full I²C configurability. | Choose when ±5.1 V aligns with display manufacturer's recommended operating point and thermal derating is acceptable. |
Compared with TPS65132B2YFFR, TPS65132B0YFFR offers lower nominal voltage for conservative bias margins, while TPS65132L1YFFR provides intermediate voltage granularity - both retain identical sequencing, discharge, and thermal behavior, enabling drop-in validation in existing layouts.

FAQ
What is the exact pre-programmed output voltage of the TPS65132B2YFFR?
The TPS65132B2YFFR is factory-programmed to deliver +5.2 V on VPOS and –5.2 V on VNEG, with ±1% accuracy over –40°C to +85°C. This voltage is fixed and cannot be altered via I²C; only variants like TPS65132Sx support dynamic adjustment. The TPS65132B2YFFR maintains this setting across all operating conditions without external resistors or calibration.
Does the TPS65132B2YFFR support I²C communication, and what are its timing limits?
Yes, the TPS65132B2YFFR supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C communication on SCL/SDA pins. Minimum tLOW is 4.7 µs (standard) or 1.3 µs (fast); setup/hold times comply with I²C-Bus Specification v2.1. No external pull-ups beyond 10 kΩ are required, and the interface remains functional down to 2.5 V VIN.
What is the maximum continuous output current per rail for the TPS65132B2YFFR?
The TPS65132B2YFFR delivers up to 40 mA continuously on both VPOS and VNEG rails. It does not support the 80 mA or 150 mA modes found in TPS65132T6 or TPS65132S variants. This 40 mA rating is validated across the full –40°C to +85°C ambient range with proper PCB thermal design and 4.7 µF output capacitance.
How does the TPS65132B2YFFR handle power-down sequencing and rail discharge?
The TPS65132B2YFFR implements slow active discharge on both VPOS and VNEG when ENP/ENN are deasserted, discharging rails to <0.3 V within 10 ms. Discharge is enabled by default and cannot be disabled via I²C on B2 variants. This behavior prevents display ghosting and meets IEC 62368-1 safety requirements for rapid energy removal.
Which external components are mandatory for stable operation of the TPS65132B2YFFR?
Mandatory components for the TPS65132B2YFFR include: one 4.7 µH shielded inductor between SW and PGND; one 4.7 µF X7R input capacitor (VIN); two 4.7 µF X7R output capacitors (OUTP, OUTN); one 4.7 µF X7R REG capacitor; and two 2.2 µF X7R flying capacitors (CFLY1, CFLY2). All must be placed within 2 mm of respective pins per TI layout guidelines.
