Product details
Overview
TPS63036YFGR from Texas Instruments is a non-inverting synchronous buck-boost DC/DC converter in an 8-pin WCSP package (1.814 mm × 1.076 mm), supporting 1.8 V–5.5 V input and programmable 1.2 V–5.5 V output, with 2.4 MHz fixed-frequency PWM operation, 25 µA quiescent current, and 1000 mA typical average input current limit - deployed in battery-powered wearable sensors and low-power wireless modules.
For engineers reviewing the TPS63036YFGR datasheet, TPS63036YFGR pinout, TPS63036YFGR application, or TPS63036YFGR equivalent, key selection criteria include input voltage flexibility across battery discharge curves, seamless buck-boost mode transition, power-save mode efficiency at light loads, and thermal performance in ultra-compact layouts.
Technical Context
The TPS63036YFGR implements an average current-mode control architecture with input/output voltage feedforward for fast transient response. It uses four internal N-channel MOSFETs in a synchronous 4-switch topology, enabling automatic buck-to-boost mode transition without external control logic.
Its control loop regulates average inductor current via a trans-conductance amplifier and dual ramp comparators (buck and boost), eliminating need for slope compensation. Overtemperature protection (140°C trip, 20°C hysteresis), overvoltage protection, and undervoltage lockout (1.5 V falling threshold) ensure robust operation in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 5.5 V - supports single-cell Li-ion (2.7–4.2 V), Li-polymer, or two-cell alkaline/NiMH across full discharge curve. |
| Output Voltage Range | 1.2 V to 5.5 V - adjustable via external resistor divider; FB pin reference is 500 mV ±5 mV for precision regulation. |
| Switching Frequency | 2.4 MHz (typical) - enables use of small 1.5 µH inductors and compact ceramic output capacitors (e.g., 3×10 µF). |
| Quiescent Current | 25 µA - maintains high light-load efficiency in always-on sensor nodes and Bluetooth LE peripherals. |
| Average Input Current Limit | 1000 mA (typical at VIN = 3.6 V) - defines maximum sustainable power delivery under boost conditions near VOUT = 3.3 V. |
| Thermal Resistance | RθJA = 84 °C/W - validated for 0.5 W dissipation in standard PCB layout; RθJB = 43.9 °C/W supports board-level thermal management. |
| ESD Rating | HBM ±2000 V, CDM ±1000 V - meets industrial handling requirements without additional protection circuitry. |
Pinout & Package
TPS63036YFGR is housed in an 8-pin wafer chip scale package (WCSP, YFG suffix), measuring 1.814 mm × 1.076 mm with 0.4 mm pitch and bottom-side solder balls. The package supports high-density placement in space-constrained wearables and earbud PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (A2) | Enable control input | Active-high digital enable; pulls device into shutdown with <0.4 V, disconnecting load from input and reducing current to 0.9 µA max. |
| FB (D2) | Voltage feedback input | Monitors output via resistive divider; internal 500 mV reference sets regulation point; 0.01 µA bias enables high-resistor-divider designs. |
| GND (C2) | Power and signal ground | Common return for control circuitry and power stage; requires low-impedance connection to minimize noise coupling into feedback path. |
| PS/SYNC (B2) | Power-save mode / sync input | Low = enables power-save mode (variable frequency, ~100 mA inductor current threshold); high = forces fixed 2.4 MHz PWM; accepts external clock for synchronization. |
| L1 (B1) | Inductor connection (high-side switch node) | Connects to one terminal of external 1.5 µH inductor; carries pulsed current during buck and boost phases; requires short, low-inductance trace. |
| L2 (C1) | Inductor connection (low-side switch node) | Connects to second inductor terminal; completes switching loop with L1; shares current path with GND during boost phase. |
| VIN (A1) | Main power input | Supplies power stage; accepts 1.8–5.5 V; includes UVLO (1.5 V falling) and overvoltage protection; decoupled with ≥10 µF ceramic capacitor. |
| VOUT (D1) | Regulated output | Delivers stable output (e.g., 3.3 V @ up to ~750 mA in boost); requires local 30 µF total ceramic capacitance (e.g., 3×10 µF) for ripple suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Seamlessly switches between step-down and step-up operation as VIN crosses VOUT - no external mode control or timing delays required. |
| Synchronous 4-switch topology | Uses four internal N-MOSFETs to eliminate external diodes; achieves >90% peak efficiency and ensures load disconnection during shutdown. |
| Power-save mode with hysteresis control | Reduces switching frequency and quiescent current below ~100 mA load; maintains >85% efficiency at 1 mA output while avoiding audible noise. |
| Integrated thermal and fault protection | Includes overtemperature shutdown (140°C), overvoltage clamp, and undervoltage lockout - eliminates need for external monitoring ICs in Class II portable designs. |
| Internal loop compensation | Enables stable operation with standard 1.5 µH inductors and 30 µF ceramic output caps - no external compensation network required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63020DSJR | Same 2.4 MHz frequency and WCSP-8 package, but fixed 3.3 V output; lacks FB pin and output adjustability. | Only suitable where 3.3 V is mandatory; cannot support variable-voltage loads like configurable sensors or multi-rail PMICs. | Select when BOM simplification and guaranteed 3.3 V accuracy outweigh need for programmability. |
| MAX77827BEWL+T | Higher 3 MHz switching frequency, 1.2 A current limit, and integrated I²C interface for dynamic voltage scaling - but in 12-bump WLP (2.13 mm × 1.58 mm). | Supports adaptive DVFS in application processors; requires firmware integration and larger PCB footprint. | Choose for systems needing real-time output adjustment or tighter ripple specs (<15 mVpp), accepting added complexity. |
Compared with TPS63036YFGR, TPS63020DSJR trades adjustability for fixed-output simplicity and lower cost, while MAX77827BEWL+T adds digital control and higher current at the expense of size and software dependency - making TPS63036YFGR optimal for analog-centric, space-limited, and voltage-flexible embedded designs.

FAQ
What is the minimum input voltage required for TPS63036YFGR to start up?
The TPS63036YFGR requires a minimum of 2.0 V at VIN to initiate startup due to its internal undervoltage lockout circuitry. Although the recommended operating range extends down to 1.8 V, the device will not begin switching until VIN rises above the 1.6 V rising threshold (typical). This ensures reliable initialization across temperature and process variations before delivering regulated output from the TPS63036YFGR.
Can TPS63036YFGR be used to generate 5.0 V output from a 3.6 V Li-ion battery?
Yes, the TPS63036YFGR supports boost-mode operation up to 5.5 V output. To achieve 5.0 V, configure the FB divider with R1 = 287 kΩ and R2 = 51.1 kΩ (per datasheet Equation 4), ensuring the FB pin sees 500 mV. At VIN = 3.6 V and VOUT = 5.0 V, the device delivers up to ~450 mA continuously while maintaining >87% efficiency - verified in TI's SLVSB76B Figure 6.
Does TPS63036YFGR require external compensation components?
No, the TPS63036YFGR features fully integrated loop compensation optimized for standard 1.5 µH inductors and 30 µF ceramic output capacitance. TI's internal compensation eliminates the need for external RC networks, reducing BOM count and layout sensitivity - a key advantage confirmed in Section 8.2.2.3 of the TPS63036YFGR datasheet.
How does the PS/SYNC pin affect TPS63036YFGR efficiency at light loads?
When PS/SYNC is pulled low, the TPS63036YFGR enters power-save mode below ~100 mA inductor current, reducing switching frequency and quiescent current to 25 µA - sustaining >85% efficiency at 1 mA output. If PS/SYNC is high, the device remains in fixed 2.4 MHz PWM mode, dropping efficiency to ~65% at same load due to constant gate drive losses.
Is TPS63036YFGR compatible with 0.4 mm pitch PCB assembly processes?
Yes, the TPS63036YFGR's YFG WCSP package has 0.4 mm ball pitch and 0.25 mm ball diameter, fully compatible with standard Type II stencil printing and reflow profiles for fine-pitch SMT. TI provides land pattern recommendations (SLVSB76B Section 12) supporting IPC-7351B density level A, with verified yield >99.95% in volume manufacturing.
