Product details
Overview
TPS62088YWCR from Texas Instruments is a high-frequency synchronous step-down DC-DC converter in a 0.8mm × 1.2mm × 0.3mm wafer chip-scale package (YWC), delivering up to 3 A output current with 4 MHz switching frequency, 1% output voltage accuracy, and 4 µA quiescent current - designed for ultra-thin embedded power rails in space-constrained portable electronics.
For engineers reviewing the TPS62088YWCR datasheet, TPS62088YWCR pinout, TPS62088YWCR application, or TPS62088YWCR equivalent, this device is selected for battery-powered systems requiring sub-0.6 mm height, high light-load efficiency via DCS-Control PFM/PWM seamless transition, and robust thermal performance in 12 mm² footprint designs.
Technical Context
The TPS62088YWCR implements TI's DCS-Control topology - a hybrid regulation scheme combining voltage-mode stability with hysteretic-like transient response - enabling both PWM mode (fixed 4 MHz) at medium/heavy loads and automatic power-save mode (variable frequency) at light loads without output voltage disturbance. Its dual 26 mΩ MOSFETs support continuous conduction and 100% duty-cycle operation for minimal dropout.
It integrates active output discharge, open-drain power-good (PG) with 92–110% threshold hysteresis, undervoltage lockout (2.2 V nominal), thermal shutdown (150 °C), and hiccup-mode short-circuit protection. The YWC package enables embedding directly into PCB substrates with 0.4 mm pitch and 0.3 mm profile.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.4 V to 5.5 V - supports single-cell Li-ion, Li-polymer, and multi-cell alkaline/NiMH battery stacks without external LDO pre-regulation. |
| Output Current | Up to 3 A - sufficient for powering core logic, memory, or RF subsystems in compact mobile devices. |
| Switching Frequency | 4 MHz - enables use of sub-0.3 µH inductors and small ceramic capacitors, reducing solution size below 12 mm². |
| Quiescent Current | 4 µA - extends battery runtime in always-on sensor or standby modes without compromising wake-up speed. |
| Output Accuracy | ±1% - ensures stable core voltage for processors and FPGAs operating at low-voltage nodes (e.g., 0.6–1.8 V). |
| Package Dimensions | 0.8 mm × 1.2 mm × 0.3 mm - lowest-profile 6-pin DSBGA available, compatible with embedded die-on-PCB assembly. |
| Thermal Resistance | RθJA = 130.9 °C/W - enables full 3 A load capability at ambient temperatures up to 85 °C with standard 2-layer board layout. |
Pinout & Package
TPS62088YWCR uses a 6-pin wafer-level chip-scale package (DSBGA, YWC variant), measuring 0.8 mm × 1.2 mm × 0.3 mm with 0.4 mm pitch. The package is optimized for embedding and ultra-low height (< 0.6 mm system stackup).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control (VIH = 1.0 V); pulling low disables converter and reduces current draw to 0.5 µA - critical for system-level power sequencing. |
| VIN | Input supply | Accepts 2.4–5.5 V; must be decoupled with ≥4.7 µF ceramic capacitor placed adjacent to pin to suppress high-frequency switching noise. |
| PG | Power-good open-drain output | Sinks up to 1 mA; requires external pullup to ≤5.5 V rail; signals valid regulation (96–105% VFB) - used for rail sequencing or fault monitoring. |
| SW | Power switch node | Connects to external inductor; carries high di/dt current - requires tight loop routing and ground plane underneath to minimize EMI and voltage spikes. |
| FB | Feedback input | Monitors output via resistor divider (or direct connection for fixed-VOUT variants); internal reference is 600 mV - sets regulation point with ±1% tolerance. |
| GND | Power and signal ground | Single ground pad; must be connected to low-impedance thermal pad on PCB - essential for thermal dissipation and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Enables seamless PWM-to-PFM transition with <5 mV load transient undershoot/overshoot - eliminates need for external compensation components. |
| 100% duty cycle operation | Extends usable battery range down to VIN ≈ VOUT + IOUT×RDS(on); maintains regulation even when input drops to 10% above output voltage. |
| Active output discharge | Internally discharges VOUT through SW pin during shutdown - prevents floating rail conditions that could damage downstream logic or cause latch-up. |
| Forced-PWM option (A variant) | TPS62088A version sustains CCM across full load range, reducing output ripple to <10 mVPP - required for noise-sensitive analog or RF circuits. |
| Hiccup short-circuit protection | Enters 128 µs auto-restart cycle after 32 current-limit events - protects against sustained overload while avoiding thermal runaway. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62088YFP | Same electrical specs but in 0.5 mm tall YFP (DSBGA) package - higher RθJA (141.3 °C/W) and no embedded compatibility. | Preferred for prototyping or non-embedded production where 0.2 mm extra height is acceptable and thermal margin is >15 °C. | Select when board-level reworkability or standard reflow compatibility outweighs ultra-low-profile requirements. |
| TPS6208818YWC | Fixed 1.8 V output (vs. adjustable TPS62088YWCR); identical YWC package, pinout, and thermal specs. | Used where output voltage is static and feedback resistors can be omitted - reduces BOM count and layout area by ~0.5 mm². | Choose for cost-sensitive volume production with unchanging VOUT; retains same footprint and mounting process. |
Compared with TPS62088YFP, TPS62088YWCR offers 0.2 mm lower profile and 8.4 °C/W better thermal resistance for embedded deployment; compared with TPS6208818YWC, it provides design flexibility for dynamic voltage scaling at the cost of two external resistors.

FAQ
What is the maximum continuous output current supported by the TPS62088YWCR?
The TPS62088YWCR supports up to 3 A of continuous output current under recommended operating conditions (TJ ≤ 125 °C). At full 3 A load, junction temperature must be monitored - lifetime derating applies above 85 °C for YFP variants, but the YWC package's lower RθJA (130.9 °C/W) sustains full rating on typical 2-layer boards with adequate copper area.
Does the TPS62088YWCR require external feedback resistors to set output voltage?
Yes, the TPS62088YWCR is an adjustable-output converter and requires external R1/R2 resistors on the FB pin to set VOUT between 0.6 V and 4.0 V per the equation VOUT = 0.6 V × (1 + R1/R2). For fixed-output alternatives like TPS6208818YWC, the FB pin connects directly to VOUT and no resistors are needed - but TPS62088YWCR mandates them for configuration.
How does the power-good (PG) pin function on the TPS62088YWCR?
The PG pin on the TPS62088YWCR is an open-drain output that goes high-impedance when VFB is within 96–105% of nominal (indicating valid regulation) and pulls low when VFB falls below 92% or rises above 110%. It sinks up to 1 mA and requires an external pullup to ≤5.5 V - commonly used to enable downstream converters or trigger system reset if regulation fails.
Can the TPS62088YWCR operate with a 2.4 V input and 1.8 V output at full 3 A load?
Yes, the TPS62088YWCR supports 2.4 V input at 3 A output with 1.8 V setting, but operates near 100% duty cycle. Under these conditions, the minimum input to sustain regulation is VIN,MIN = VOUT + IOUT,MAX × RDS(on) ≈ 1.8 V + 3 A × 0.026 Ω = 1.878 V - well below 2.4 V, confirming stable operation. Efficiency remains >85% per typical curves at this condition.
Is the TPS62088YWCR pin-compatible with other members of the TPS62088x family?
Yes, all TPS62088x variants - including TPS62088YFP, TPS62088A, TPS62089A, and TPS6208818YWC - share identical 6-pin YWC/YFP DSBGA footprints and pin assignments (EN, VIN, PG, SW, FB, GND). This allows drop-in replacement across adjustable/fixed, PFM/PWM, and 2 A/3 A versions without PCB redesign - provided thermal and layout constraints are verified for each variant's RθJA and current rating.
