Product details
Overview
TPS62089AYFPR from Texas Instruments is a forced-PWM, synchronous step-down DC-DC converter delivering up to 2 A output current with 4 MHz switching frequency, 1% output voltage accuracy, and 4 µA quiescent current - designed for space-constrained embedded power rails in camera modules and optical modules.
For engineers reviewing the TPS62089AYFPR datasheet, TPS62089AYFPR pinout, TPS62089AYFPR application, or TPS62089AYFPR equivalent, key selection criteria include its 2-A current rating, YWC wafer chip-scale package (0.8 mm × 1.2 mm × 0.3 mm), DCS-Control topology for seamless light-load efficiency, active output discharge, and power-good signaling - all critical for ultra-thin battery-powered systems.
Technical Context
The TPS62089AYFPR implements DCS-Control topology with fixed on-time PWM regulation, maintaining continuous conduction mode (CCM) across full load range and delivering stable 4 MHz operation regardless of input or load variation. Its dual 26 mΩ internal MOSFETs enable high-efficiency conversion from 2.4 V to 5.5 V input down to 0.6 V–4.0 V adjustable output.
It integrates undervoltage lockout (2.2 V threshold), thermal shutdown (150 °C), hiccup-mode short-circuit protection, and 100% duty-cycle low-dropout operation - enabling full battery utilization in wearable and mobile applications where height (<0.6 mm) and footprint (<12 mm²) are constrained.
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 3.3 V/5 V system rails without external LDO pre-regulation. |
| Output Current | 2 A maximum - validated for continuous operation at TJ ≤ 125 °C in YWC package with proper PCB thermal relief. |
| Switching Frequency | 4 MHz - enables use of sub-0.3 µH inductors and compact 0402/0603 ceramic capacitors to minimize solution size. |
| Quiescent Current | 4 µA - ensures minimal battery drain during standby in always-on sensor or camera subsystems. |
| Output Accuracy | ±1% - guarantees tight regulation for noise-sensitive analog circuits like image sensors and RF front-ends. |
| Package Dimensions | 0.8 mm × 1.2 mm × 0.3 mm - ultra-low-profile wafer chip-scale package (YWC) suitable for embedded PCB construction. |
| Internal FET RDS(on) | 26 mΩ high-side + 26 mΩ low-side - reduces conduction loss and thermal rise in high-current, low-VOUT configurations. |
Pinout & Package
TPS62089AYFPR uses a 6-pin DSBGA wafer chip-scale package (YWC) with 0.4 mm pitch and 0.3 mm profile, optimized for embedding beneath components or within thin mobile modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control; requires ≥1.0 V to enable; must not float - used for sequencing and dynamic power gating. |
| VIN | Input supply | Primary power input (2.4–5.5 V); connects to bulk capacitor near package for low-impedance path and EMI reduction. |
| PG | Power-good open-drain | Signals valid output regulation (96–105% VFB); requires external pullup ≤5.5 V; used for rail sequencing and fault monitoring. |
| SW | Switch node | Connects to inductor and catch diode path; high dv/dt node requiring tight layout and ground shielding to minimize EMI. |
| FB | Feedback input | Resistive divider input for adjustable output (0.6–4.0 V); internal 600 mV reference enables precise voltage setting. |
| GND | Ground reference | Power and signal return; must be connected to low-impedance thermal pad and solid ground plane for thermal and noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| Forced-PWM operation | Maintains CCM across entire load range, eliminating audible noise and ensuring predictable EMI spectrum for RF-coexistence designs. |
| DCS-Control topology | Enables seamless transition between PWM and power-save modes without output voltage disturbance - critical for transient-sensitive imaging pipelines. |
| Active output discharge | Internally discharges VOUT when disabled via SW pin, preventing floating rail conditions that could damage downstream logic or cause latch-up. |
| 100% duty cycle mode | Extends battery runtime by sustaining regulation down to VIN ≈ VOUT + IOUT×RDS(on), maximizing usable voltage from depleted cells. |
| Thermal & short-circuit protection | Hiccup-mode current limiting and 150 °C thermal shutdown prevent permanent damage during overloads or solder shorts in automated assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62088AYFPR | 3-A rated, same YWC package and pinout, identical features except higher current limit (4.3 A typical vs. 3.3 A for TPS62089AYFPR). | Supports higher-power SoCs or multi-rail designs where >2 A peak current is required. | Select when system peak load exceeds 2 A but board space and height constraints remain identical. |
| TPS62095YFPR | Same 2-A rating and YWC package, but operates at 2.5 MHz (not 4 MHz); lacks active output discharge and has 10 µA IQ. | Better suited for cost-sensitive or thermally relaxed layouts where smaller inductors are not mandatory. | Choose if 4 MHz EMI filtering is unnecessary and lower BOM cost outweighs height/size advantages of TPS62089AYFPR. |
Compared with TPS62088AYFPR, TPS62089AYFPR trades 1 A of output capability for tighter thermal margin in ultra-thin packages; versus TPS62095YFPR, it delivers superior light-load efficiency, lower profile, and faster transient response - making it optimal for next-gen compact imaging and sensing platforms.

FAQ
What is the maximum continuous output current supported by the TPS62089AYFPR?
The TPS62089AYFPR is rated for 2 A continuous output current under recommended operating conditions (TJ ≤ 125 °C). Its current limit is specified at 2.7–3.9 A typical, and thermal performance in the YWC package allows sustained 2-A operation with adequate PCB copper area and airflow. Exceeding 2 A continuously may trigger thermal shutdown or reduce lifetime reliability.
Does the TPS62089AYFPR support adjustable output voltage, and what is the range?
Yes, the TPS62089AYFPR supports adjustable output voltage from 0.6 V to 4.0 V using an external resistor divider on the FB pin. Its internal feedback reference is 600 mV ±1%, enabling precise regulation. Fixed-output variants exist (e.g., TPS62089A12), but TPS62089AYFPR is the adjustable version - confirmed by TI's device options table and electrical characteristics section.
What package type and dimensions does the TPS62089AYFPR use?
The TPS62089AYFPR uses the YWC package: a 6-pin DSBGA wafer chip-scale package measuring 0.8 mm × 1.2 mm × 0.3 mm nominal, with 0.4 mm ball pitch. This ultra-low-profile package is explicitly designated for embedded applications and supports <0.6 mm system height - distinct from the taller YFP variant (0.5 mm).
How does the forced-PWM mode of the TPS62089AYFPR differ from PFM/PWM auto-mode devices?
The forced-PWM mode in the TPS62089AYFPR maintains continuous conduction mode (CCM) and fixed 4 MHz switching across all load conditions - unlike PFM/PWM devices that skip pulses at light loads. This eliminates low-frequency output ripple and audible noise, improves EMI predictability, and ensures consistent transient response, which is essential for powering clock-sensitive analog blocks in camera and optical modules.
Is active output discharge integrated in the TPS62089AYFPR, and how does it function?
Yes, the TPS62089AYFPR includes active output discharge. When EN is pulled low, an internal switch connects the SW node to GND, discharging the output capacitor through the inductor and low-side FET path. This prevents residual voltage from causing unintended operation or latch-up in downstream logic - a critical feature for safe power sequencing in portable electronics.
