Product details
Overview
TPS62300DRCR from Texas Instruments is an adjustable-output, 3-MHz synchronous step-down DC-DC converter in a 10-pin QFN (3 × 3 mm) package. It delivers up to 500 mA output current with 86 µA quiescent current, 35 ns minimum on-time, and ±0.5%/+1.3% DC voltage accuracy over temperature. Designed for single-cell Li-Ion or 3-cell NiMH/NiCd battery-powered portable electronics, it supports output voltages from 0.6 V to 5.4 V.
For engineers reviewing the TPS62300DRCR datasheet, TPS62300DRCR pinout, TPS62300DRCR application, or TPS62300DRCR equivalent, key selection criteria include its fixed 3-MHz switching frequency, power-save mode operation at light loads, on-the-fly synchronization capability, and compatibility with low-profile 1-µH inductors and 4.7-µF ceramic capacitors in space-constrained designs.
Technical Context
The TPS62300DRCR employs a voltage-mode PWM controller with input voltage feed-forward for fast load and line transient response. Its dual MOSFET power stage integrates P-channel (750 mΩ typical rDS(on)) and N-channel (750 mΩ typical rDS(on)) switches with independent current limiting-670–890 mA for P-MOS and 550–890 mA for N-MOS-enabling stable operation across wide duty cycles including 100% dropout.
Operation includes automatic transition between fixed-frequency PWM (moderate/heavy loads) and pulse-frequency modulation (PFM) power-save mode (light loads), triggered at ~1–5 mA depending on inductor value. The MODE/SYNC pin enables forced PWM, external clock synchronization (2.65–3.35 MHz), or automatic PFM/PWM mode selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Switching frequency | 3 MHz fixed - enables use of sub-1-µH inductors and reduces EMI filter size |
| Input voltage range | 2.7 V to 6 V - compatible with single Li-Ion (2.7–4.2 V) and 3-cell NiMH (3.0–4.5 V) |
| Quiescent current | 86 µA in PFM mode - extends battery life in standby/sleep states |
| Output voltage range | 0.6 V to 5.4 V adjustable - covers DSP, MCU, FPGA, and memory supply requirements |
| DC voltage accuracy | ±0.5% / +1.3% over –40°C to +85°C - ensures stable regulation across thermal environments |

Pinout & Package
TPS62300DRCR is housed in a thermally enhanced 10-pin QFN package (3 mm × 3 mm, 0.5 mm pitch) with exposed PowerPAD™ connected internally to PGND. Pin 1 is VIN (top-left corner, marked dot).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Main supply rail for power stage; requires local 4.7 µF ceramic bypass capacitor |
| AVIN | Analog input | Separate analog supply input for internal reference and control circuitry |
| EN | Enable control | Active-high logic input; <0.4 V disables device (<1 µA shutdown current) |
| ADJ | Output voltage programming | Adjustable feedback node; sets VOUT = 1.5 × VADJ; not used in fixed-output variants |
| FB | Feedback sense | Internal 0.4 V reference input; connects to resistor divider for output voltage setting |
| VOUT | Output sense | Direct connection to regulated output node for remote sensing and stability |
| AGND | Analog ground | Reference ground for feedback and control circuits; tied to PGND via PowerPAD™ |
| MODE/SYNC | Mode control & sync | GND = auto PFM/PWM; VIN = forced PWM; external 3-MHz clock = synchronization |
| PGND | Power ground | High-current return path for power stage; must be low-inductance connection |
| SW | Switch node | Drain connection of internal P/N-MOSFETs; connects to inductor and catch diode (if used) |
Key Features

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 |
|---|---|---|---|
| TPS62320DRCR | Same QFN-10 package and 3-MHz operation, but includes integrated active power-down sequencing (30–50 Ω discharge resistor) and tighter UVLO (2.4 V vs. 2.4 V) | Required where controlled output discharge during shutdown is mandatory (e.g., FPGA configuration retention) | Select TPS62320DRCR when active discharge is needed; otherwise TPS62300DRCR offers identical regulation and efficiency |
| TPS62303DRCR | Fixed 1.8 V output (vs. adjustable), same QFN-10 package, 3-MHz operation, 500 mA rating, and identical quiescent current | Suitable for systems with static 1.8 V I/O or memory rails where external feedback resistors are undesirable | Choose TPS62303DRCR to eliminate external resistors and simplify layout for fixed 1.8 V outputs |
Compared with TPS62320DRCR and TPS62303DRCR, the TPS62300DRCR provides full output voltage adjustability (0.6–5.4 V) without integrated discharge circuitry-making it optimal for cost-sensitive, space-constrained applications where programmability and minimal BOM count are prioritized over active shutdown discharge.

FAQ
What is the maximum continuous output current supported by the TPS62300DRCR?
The TPS62300DRCR supports a maximum continuous output current of 500 mA across its full operating temperature range (–40°C to +85°C). This rating assumes proper PCB thermal design with adequate copper pour connected to the PowerPAD™ and ambient temperature ≤85°C. Derating applies above 25°C ambient per the RθJA = 49°C/W specification.
Does the TPS62300DRCR require external compensation components?
No, the TPS62300DRCR uses an internally compensated voltage-mode control architecture and requires no external compensation components. Stability is ensured with standard 4.7 µF ceramic output capacitors and 1 µH shielded inductors. The device's feed-forward design and fixed 3-MHz frequency eliminate loop compensation complexity.
Can the TPS62300DRCR be synchronized to an external clock signal?
Yes, the TPS62300DRCR can be synchronized to an external clock signal via the MODE/SYNC pin. When driven with a 2.65–3.35 MHz square wave (20–80% duty cycle), the device locks its switching frequency to the external source and aligns P-channel turn-on to the falling edge-enabling deterministic multi-rail timing in noise-sensitive systems.
What is the purpose of the ADJ pin on the TPS62300DRCR?
The ADJ pin on the TPS62300DRCR serves two functions: (1) as the adjustable feedback node-where a resistor divider sets VOUT = 0.4 V × (1 + R1/R2); and (2) as a direct voltage programming input-where VOUT = 1.5 × VADJ. It is unconnected in fixed-output variants but essential for output flexibility in the TPS62300DRCR.
How does the TPS62300DRCR handle startup and undervoltage lockout?
The TPS62300DRCR features internal soft-start (250 µs typical rise time) and a 2.4 V undervoltage lockout (UVLO) threshold with hysteresis. Startup begins only when VIN exceeds 2.4 V; if VIN drops below 2.4 V during operation, the device shuts down and remains off until VIN rises above 2.55 V, preventing erratic behavior during brownout conditions.
