Product details
Overview
TPS62201DBVRG4 from Texas Instruments is a fixed-output, synchronous step-down DC-DC converter delivering 1.5 V at up to 300 mA, operating from 2.5 V to 6 V input, with 1 MHz fixed-frequency PWM and power-save mode for high efficiency across load range. It serves as the core voltage regulator for low-power DSPs and microcontrollers in battery-powered portable electronics.
For engineers reviewing the TPS62201DBVRG4 datasheet, TPS62201DBVRG4 pinout, TPS62201DBVRG4 application, or TPS62201DBVRG4 equivalent, key selection criteria include its 15 µA typical quiescent current in power-save mode, ±3% output voltage accuracy over temperature and load, SOT-23-5 package footprint, and integrated P/N-channel MOSFETs eliminating external switch requirements.
Technical Context
The TPS62201DBVRG4 implements a fast-response voltage-mode control architecture with input voltage feed-forward, enabling stable regulation using only small ceramic capacitors (4.7 µF input, 10 µF output). Its dual-mode operation-fixed-frequency PWM at medium-to-heavy loads and pulse-frequency modulation (PFM) at light loads-maintains >90% efficiency from 1 mA to 300 mA.
Internal undervoltage lockout (1.5–2.0 V threshold), soft-start (800 µs typical with 10 µF output cap and 200 mA load), and 100% duty-cycle low-dropout operation allow full utilization of declining battery voltage. The device integrates both power switches and requires no external compensation components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±3% over 0–300 mA load and –40°C to +85°C ambient - ensures stable core supply for 1.5 V logic domains. |
| Input Voltage Range | 2.5 V to 6.0 V - supports single-cell Li-ion (2.7–4.2 V), 3-cell NiMH/NiCd (3.6–4.5 V), and standard 3.3 V/5 V rails. |
| Max Output Current | 300 mA continuous - sufficient for low-power DSPs, ARM Cortex-M0/M3 cores, and sensor hubs. |
| Switching Frequency | 650–1500 kHz (typ. 1 MHz) - enables compact 10 µH inductor and minimal EMI filtering. |
| Quiescent Current | 15 µA typical in power-save mode - extends battery life in standby/sleep states without sacrificing wake-up response. |
| Enable Threshold | EN high ≥1.3 V, EN low ≤0.4 V - compatible with 1.8 V/3.3 V GPIOs; shutdown current <1 µA. |
| Thermal Resistance | RθJA = 220°C/W (SOT-23-5) - requires minimal PCB copper for thermal relief in space-constrained layouts. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads, JEDEC MO-178AC compliant. Thermal pad not present; PCB land pattern per TI SLVS417F.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VI | Input supply rail | Accepts 2.5–6 V; must be decoupled with ≥4.7 µF ceramic capacitor placed adjacent to pin. |
| 2 - GND | Power ground reference | Low-impedance return path for input/output currents; connects directly to PCB ground plane. |
| 3 - EN | Enable control input | Active-high logic; pull to VI for operation, to GND for <1 µA shutdown; must not float. |
| 4 - FB | Feedback sense node | Internally connected to 0.5 V reference; for fixed-output TPS62201, tied directly to output; no external divider required. |
| 5 - SW | Switch node | Drives external inductor; carries high di/dt pulsed current; requires tight layout to minimize EMI and voltage spikes. |
Key Features
| Feature | Design Value |
|---|---|
| High-efficiency synchronous conversion | Up to 95% peak efficiency at 200 mA (VI = 3.7 V, VO = 1.5 V) - reduces thermal load and extends battery runtime. |
| Dynamic output-voltage positioning | Output rises ~0.8% above nominal under light load, providing headroom for transient load steps without undershoot. |
| Integrated soft-start | 800 µs typical startup time with 10 µF output cap and 200 mA load - prevents input rail collapse during power-up. |
| 100% duty-cycle operation | Maintains regulation down to VI = VO + IOUT × rDS(ON)_P - enables full discharge of Li-ion batteries to ~2.8 V. |
| Low-noise voltage-mode control | No external compensation needed; stable with 10 µF ceramic output cap - simplifies design and saves board area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62200DBVR | Adjustable output (0.7–VI) via external resistor divider; same 300 mA rating, 1 MHz, and SOT-23-5 package. | Requires two external resistors and optional noise-reduction capacitors; less suitable for cost-sensitive fixed-voltage designs. | Select when output voltage flexibility or future design reuse across multiple rails is required. |
| TPS62202DBVR | Fixed 1.8 V output; identical specs otherwise - same IQ, efficiency curve, EN behavior, and thermal performance. | Not interchangeable without PCB redesign due to different feedback network (FB tied to 1.8 V vs 1.5 V). | Choose only if system requires 1.8 V logic rail; not a drop-in replacement for TPS62201DBVRG4. |
Compared with TPS62200DBVR and TPS62202DBVR, the TPS62201DBVRG4 provides optimal balance of simplicity (no external resistors), precision (1.5 V fixed), and compatibility with legacy 1.5 V microcontroller families - making it the preferred choice where output voltage is fixed and board space is constrained.

FAQ
What is the output voltage tolerance of the TPS62201DBVRG4 over temperature and load?
The TPS62201DBVRG4 maintains ±3% output voltage accuracy across its full operating range: –40°C to +85°C ambient temperature and 0–300 mA output current. This specification is verified per TI SLVS417F datasheet Section 6.5, Table "Feedback voltage (1)" for TPS62201, ensuring reliable 1.5 V regulation for sensitive logic circuits without external trimming.
Does the TPS62201DBVRG4 require external compensation components?
No, the TPS62201DBVRG4 uses an internal voltage-mode control loop with feed-forward architecture that eliminates the need for external compensation. As confirmed in Section 7.1 and Figure 7 of the SLVS417F datasheet, stability is achieved with only a 10 µF ceramic output capacitor and 4.7 µF input capacitor - reducing BOM count and layout complexity.
Can the TPS62201DBVRG4 operate with a 2.5 V input and deliver 1.5 V at 300 mA?
Yes, the TPS62201DBVRG4 supports 2.5 V minimum input and delivers full 300 mA at 1.5 V output. Its 100% duty-cycle capability and low rDS(ON) P-channel switch (670 mΩ max at 2.5 V) ensure regulation even at the lowest input, as validated in Section 7.3.4 and electrical characteristics tables of SLVS417F.
What is the shutdown current of the TPS62201DBVRG4 when EN is pulled low?
When the EN pin is pulled to GND, the TPS62201DBVRG4 enters shutdown mode with a typical supply current of 0.1 µA and maximum of 1 µA, per Section 6.5 "Shutdown supply current" in the SLVS417F datasheet. Both internal MOSFETs are turned off, and the feedback divider is disconnected to prevent leakage paths.
Is the TPS62201DBVRG4 pin-compatible with other devices in the TPS6220x family?
Yes, all TPS6220x variants - including TPS62200, TPS62201, TPS62202, TPS62203, TPS62204, TPS62205, TPS62207, and TPS62208 - share identical SOT-23-5 (DBV) pinout and package dimensions (2.90 mm × 1.60 mm), as documented in Section 2 "Device Information" and Figure 3 of SLVS417F.
