Product details
Overview
TPS62300YZDR from Texas Instruments is an adjustable-output, 3-MHz synchronous step-down DC-DC converter in an 8-pin NanoFree™ CSP package. It delivers up to 500 mA output current with 0.6 V to 5.4 V programmable output voltage, 86 µA quiescent current, and 93% peak efficiency-optimized for battery-powered portable devices including smartphones and PDAs.
For engineers reviewing the TPS62300YZDR datasheet, TPS62300YZDR pinout, TPS62300YZDR application, or TPS62300YZDR equivalent, key selection criteria include its 3-MHz fixed-frequency operation, power-save mode for light-load efficiency, 35-ns minimum on-time, ±0.5%/+1.3% DC voltage accuracy over temperature, and support for external synchronization via MODE/SYNC pin.
Technical Context
The TPS62300YZDR employs a voltage-mode PWM controller with input voltage feed-forward for fast transient response and stable regulation across line and load variations. Its dual MOSFET power stage integrates P-channel (750 mΩ typ) and N-channel (750 mΩ typ) switches with independent current limits (670–890 mA P-MOS, 550–890 mA N-MOS), enabling robust operation during startup and low-duty-cycle conditions.
Operation dynamically shifts between fixed-frequency PWM at moderate-to-heavy loads and pulse-frequency modulation (PFM) power-save mode at light loads-triggered automatically below ~1–5 mA depending on inductor value. The MODE/SYNC pin supports three states: GND (auto PFM/PWM), VIN (forced PWM), or external 2.65–3.35 MHz clock (synchronized PWM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion (3.0–4.2 V) and 3-cell NiMH/NiCd (3.6 V nominal) battery inputs without pre-regulation. |
| Output Voltage Range | 0.6 V to 5.4 V - adjustable via external resistor divider on FB/ADJ pins; enables direct supply to low-voltage DSPs, cores, and I/O rails. |
| Switching Frequency | 3 MHz (±0.35 MHz) - enables use of sub-1 µH inductors and compact 4.7 µF ceramic output capacitors for ultra-thin mobile designs. |
| Quiescent Current | 86 µA - ensures minimal battery drain in standby/sleep modes of handheld devices. |
| Output Current | 500 mA continuous - sufficient for RF transceivers, baseband processors, and camera modules in compact form factors. |
| DC Voltage Accuracy | ±0.5% / +1.3% over –40°C to +85°C - meets tight regulation requirements for sensitive analog and mixed-signal circuits. |
| Minimum On-Time | 35 ns - supports high step-down ratios (e.g., 5 V → 1.2 V at 3 MHz) without pulse skipping or instability. |
Pinout & Package
TPS62300YZDR uses an 8-pin NanoFree™ Chip Scale Package (CSP), measuring 1.5 mm × 1.5 mm with 0.5-mm pitch, optimized for space-constrained portable PCB layouts. The package features bottom-side solder bumps and requires standard reflow profiles per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power Input | Main input supply connection; must be decoupled locally with ≥4.7 µF ceramic capacitor to PGND. |
| EN | Enable Control | Active-high logic input; pulling to GND disables device and reduces shutdown current to <1 µA. |
| ADJ | Adjust Reference | Configures output voltage as VO = 1.5 × VADJ; used with external resistor divider for adjustable regulation. |
| FB | Feedback Sense | Internal 0.4 V reference node; connects to resistor divider midpoint for closed-loop output voltage control. |
| VOUT | Output Sense | Direct connection to regulated output rail; provides feedback path for stability and load transient compensation. |
| MODE/SYNC | Mode Control | Selects auto PFM/PWM (GND), forced PWM (VIN), or external clock sync (2.65–3.35 MHz square wave). |
| PGND | Power Ground | High-current return path for internal MOSFETs; must be connected to solid ground plane under IC. |
| SW | Switch Node | Drain connection of internal P- and N-MOSFETs; routes to external inductor and requires tight layout to minimize EMI. |
Key Features
| Feature | Design Value |
|---|---|
| 3-MHz Fixed-Frequency Operation | Enables consistent EMI profile and simplifies filtering in noise-sensitive RF sections of mobile handsets. |
| Power-Save Mode at Light Load | Maintains >85% efficiency down to 1 mA load by switching to PFM, extending battery life in display-off or idle states. |
| Integrated Active Power-Down Sequencing | Ensures controlled output discharge during shutdown via internal 30–50 Ω discharge resistor (TPS6232x only; not applicable to TPS62300YZDR). |
| 100% Duty Cycle Capability | Supports dropout operation down to VI − VO = 0 V, allowing regulation even as battery voltage declines near end-of-discharge. |
| Synchronizable On-the-Fly | Allows dynamic switching between internal oscillator and external master clock without output disturbance-critical for multi-rail synchronized power systems. |

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 |
|---|---|---|---|
| TPS62320YZDR | Same 8-pin CSP package and 3-MHz operation, but includes integrated active power-down sequencing and 2 V UVLO (vs. 2.4 V). | Required where controlled output discharge during shutdown is needed (e.g., FPGA or ASIC power sequencing). | Select TPS62320YZDR if active discharge and lower UVLO threshold are mandatory; otherwise TPS62300YZDR offers identical regulation performance at lower cost. |
| TPS62303YZDR | Fixed 1.8 V output (non-adjustable), same CSP-8 package, identical electrical specs except output voltage and FB/ADJ pin function. | Suitable for systems with fixed 1.8 V rail requirements (e.g., memory I/O, certain RF ICs) where external resistor network is undesirable. | Choose TPS62303YZDR to eliminate external feedback resistors and simplify BOM; TPS62300YZDR retains full adjustability for multi-rail flexibility. |
Compared with TPS62320YZDR and TPS62303YZDR, the TPS62300YZDR uniquely balances full output adjustability, ultra-low quiescent current, and minimal footprint-making it optimal for space- and battery-life-constrained portable designs requiring flexible voltage rails.

FAQ
What is the recommended input capacitor for TPS62300YZDR?
The TPS62300YZDR requires a minimum 4.7 µF X5R/X7R ceramic capacitor placed as close as possible to the VIN and PGND pins. TI recommends using two 2.2 µF capacitors in parallel-one near VIN and one near SW-to reduce high-frequency ripple and improve EMI performance. The capacitor must have low ESL and be rated for ≥6.3 V DC.
Does TPS62300YZDR support output voltage adjustment below 1.0 V?
Yes, the TPS62300YZDR supports output voltages from 0.6 V to 5.4 V via external resistor divider on the FB and ADJ pins. For sub-1.0 V operation, TI recommends using precision 1% resistors and routing the FB trace away from noisy nodes to maintain regulation accuracy within ±0.5%/+1.3% over temperature.
How does the MODE/SYNC pin affect efficiency in TPS62300YZDR?
When MODE/SYNC is grounded, TPS62300YZDR operates in automatic PFM/PWM mode-achieving >85% efficiency at 1 mA and >93% at 500 mA. Pulling MODE/SYNC high forces fixed-frequency PWM, reducing light-load efficiency to ~70% at 1 mA but eliminating frequency variation for EMI-sensitive applications.
Can TPS62300YZDR be used with a 0.9 µH inductor?
Yes, the TPS62300YZDR is validated with 0.9 µH inductors (e.g., FDK MIPW3226 series) and achieves stable operation and excellent transient response. Using 0.9 µH instead of 1 µH or 2.2 µH allows further reduction in solution size and maintains >90% efficiency across 10–500 mA loads when paired with 4.7 µF output capacitance.
What is the thermal performance of TPS62300YZDR in CSP-8 package?
The TPS62300YZDR in CSP-8 has a junction-to-ambient thermal resistance (RθJA) of 250°C/W on a standard 1-layer JEDEC board. At 500 mA output and 3.6 V input, typical power dissipation is ~350 mW, resulting in ~88°C junction rise above ambient-well within the 150°C maximum rating. Use of thermal vias under the PGND pad improves heat transfer significantly.
