Typical Applications
TPS62200DBVR is suitable for 6 applications: Portable Battery-Powered Systems, DSP and MCU Core Power, Point-of-Load Conversion from 3.3 V or 5 V Rails, Industrial Sensor and IoT Nodes, Display and LED Bias Rails, Audio Codec and Signal Chain Supply.
Portable Battery-Powered Systems
The TPS62200DBVR is ideally suited for portable systems powered by 1-cell Li-Ion or 3-cell NiMH/NiCd batteries, per TI product data. Its 2.5 V to 6 V input spans the full Li-Ion discharge curve (about 2.7 V to 4.2 V), while up to 95% efficiency maximizes runtime compared with LDO solutions that dissipate the voltage difference as heat. Placed as a front-end converter feeding low-voltage loads, it uses a 2.2 uH inductor and 4.7 uF ceramic capacitors thanks to 1 MHz fixed-frequency PWM operation, keeping the solution compact for handheld and wearable form factors.
Recommended
DSP and MCU Core Power
TI specifies the TPS6220x family as ideal for powering low-voltage DSPs and processors. The adjustable 0.7 V to 6 V output covers modern DSP core and I/O rails via an external resistor divider on the FB pin, while the 300 mA output current suits single-core DSP or MCU rails. Synchronous rectification maintains efficiency across wide load current ranges, important for processors with large active-to-sleep load transitions. The EN pin enables simple power sequencing when paired with a supervisor or another rail's power-good signal, and the SOT-23-5 footprint fits dense point-of-load layouts near the processor.
Recommended
Point-of-Load Conversion from 3.3 V or 5 V Rails
The TPS62200DBVR operates directly from standard 3.3 V or 5 V system rails as a local point-of-load converter, according to TI product documentation. Down-converting 5 V to lower logic rails at up to 95% efficiency avoids the heat penalty of linear regulation (5 V to 1.8 V at 300 mA would dissipate nearly 1 W in an LDO versus tens of milliwatts of loss here). The 1 MHz PWM frequency permits a 2.2 uH inductor and small ceramic output capacitors, and the DBV SOT-23-5 package places the converter close to the consuming load for tight transient response.
Recommended
Industrial Sensor and IoT Nodes
In industrial IoT sensor nodes powered from a 5 V rail or battery pack, the TPS62200DBVR supplies efficient, compact power for microcontrollers and RF modules. The 2.5 V to 6 V input tolerates wide battery sag conditions, and the synchronous architecture's efficiency over wide load currents suits duty-cycled nodes that sleep at microamp levels and burst-transmit at up to 300 mA. Its small SOT-23-5 footprint and minimal external count (inductor plus two capacitors) fit tightly constrained sensor PCBs, while the fixed 1 MHz switching keeps EMI away from sensitive analog front-end bands.
Recommended
Display and LED Bias Rails
The adjustable 0.7 V to 6 V output range lets the TPS62200DBVR generate display bias rails for small LCD and OLED modules from 5 V or Li-Ion inputs. Per TI data, the converter's 95% peak efficiency and 300 mA capability cover backlight driver and panel logic loads common in portable displays. Using the FB divider, designers set exactly the rail voltage the display module requires without sourcing a dedicated fixed-output regulator. Keep the 1 MHz switching node away from display analog lines and shield the SW trace to minimize visible ripple coupling into panel bias circuits.
Recommended
Audio Codec and Signal Chain Supply
For portable audio devices, the TPS62200DBVR efficiently steps Li-Ion battery voltage down to analog codec rails. According to TI family data, the 1 MHz fixed PWM frequency places switching ripple far above the audio band, and adding a small LC filter or feeding an LDO (such as TLV713) after the buck achieves very clean analog rails. Synchronous operation at up to 95% efficiency preserves battery life in headphone and speaker applications. The 300 mA rating supports codec plus small amplifier loads, making the DBV-package buck a compact front stage in two-stage audio power architectures.

Key Differentiators
- Adjustable output 0.7 V to 6 V (vs TPS62205DBVR)
- High synchronous efficiency (vs Asynchronous SOT-23-5 bucks)
- Fixed 1 MHz PWM operation (vs NCP1529AS)
Design Notes
Place the input capacitor (typically 4.7 uF ceramic) as close as possible to VIN (pin 5) and GND (pin 2), and the output capacitor near the inductor output. Keep the SW (pin 1) node trace short and away from the FB (pin 3) trace to prevent switching-noise coupling into the feedback loop. Use solid ground pour under the converter; at 1 MHz, loop area directly controls EMI.
For adjustable output, set VOUT = 0.7 V * (1 + R1/R2) using 1%-tolerance resistors; keep the divider current in the tens of microamps range to avoid excessive quiescent drain in battery applications. Select a 2.2 uH inductor with saturation current above 300 mA peak-plus-margin and low DCR for best efficiency.
Do not exceed the 6 V maximum input rating - 5 V USB or Li-Ion inputs are fine, but unregulated adapters may overshoot. If substituting a fixed-output family member (TPS62205, TPS62207), confirm the fixed voltage matches the rail before swapping; the parts are pin-compatible but not output-equivalent. Verify the EN pin is driven high for startup.
