Product details
Overview
TPS62007DGSG4 from Texas Instruments is a synchronous step-down DC-DC converter optimized for low-power portable systems, delivering up to 600 mA output current with 95% peak efficiency at 3.6 V input and 2.5 V output. It operates from 2 V to 5.5 V input, supports adjustable or fixed 3.3 V output, and features pin-programmable current limit (600 mA/1.2 A) and external clock synchronization up to 1 MHz. It is used in USB-based DSL modems and other network interface cards requiring stable, low-noise power regulation.
For engineers reviewing the TPS62007DGSG4 datasheet, TPS62007DGSG4 pinout, TPS62007DGSG4 application, or TPS62007DGSG4 equivalent, key selection criteria include its 750 kHz typical switching frequency, 50 µA quiescent current in PFM mode, 100% duty cycle capability for low-dropout operation, integrated antiringing switch (in fixed-output variants), and VSSOP-10 (DGS) package compatibility with space-constrained PCB layouts.
Technical Context
The TPS62007DGSG4 implements a current-mode PFM/PWM control architecture: it operates in fixed-frequency PWM mode under moderate-to-heavy loads and automatically transitions to variable-frequency pulse-frequency modulation (PFM) below ~120 mA load to maintain high light-load efficiency. Its internal compensation eliminates need for external compensation components.
It integrates complementary P-channel and N-channel MOSFETs with on-resistances of 200–410 mΩ (P-ch) and 200–410 mΩ (N-ch) at 3.6 V, supports 100% duty cycle for ultra-low dropout, and includes undervoltage lockout (~1.6 V threshold), soft-start (~1 ms), and open-drain power-good (PG) monitoring with 92% nominal VOUT threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2 V to 5.5 V - supports single-cell Li-ion (2.7–4.2 V) and dual/triple alkaline/NiMH batteries without external LDO pre-regulation. |
| Output Voltage | Fixed 3.3 V ±3% - factory-trimmed reference ensures accuracy across load and temperature without external feedback resistors. |
| Max Output Current | 600 mA (ILIM = GND) - sufficient for powering baseband processors, USB PHYs, and low-power FPGAs in portable networking gear. |
| Quiescent Current | 50 µA (typical, PFM mode) - enables >1000-hour battery life in always-on standby applications like DSL modem wake-on-ring circuits. |
| Switching Frequency | 750 kHz (typical, free-running); 500–1000 kHz (synchronized) - allows use of compact 10 µH inductors and reduces EMI filtering burden. |
| Efficiency | 95% at 3.6 VIN/2.5 VOUT/200 mA - minimizes thermal rise in sealed enclosures and extends runtime in battery-powered DSL modems. |
| Package | VSSOP-10 (DGS), 3.0 mm × 3.0 mm - surface-mount footprint compatible with automated assembly and thermal relief via PGND pad. |
Pinout & Package
VSSOP-10 (DGS) package: 3.00 mm × 3.00 mm body, 0.5 mm lead pitch, exposed thermal pad (PGND-connected), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Power input | Accepts 2–5.5 V supply; requires 10 µF ceramic input capacitor placed near pin for high-frequency decoupling. |
| FC (Pin 2) | Input bypass | High-frequency supply filter node; must connect 0.1 µF capacitor directly to VIN to suppress switching noise. |
| GND (Pin 3) | Analog ground | Reference for internal error amplifier and comparators; separate from PGND to minimize noise coupling. |
| PG (Pin 4) | Power-good indicator | Open-drain output active high when VOUT ≥92% of nominal; requires external pull-up to VOUT for status monitoring. |
| FB (Pin 5) | Feedback input | Internally connected to 3.3 V divider; unused in fixed-output TPS62007 - leave unconnected per datasheet. |
| ILIM (Pin 6) | Current limit select | Logic level input: GND = 600 mA limit, VIN = 1.2 A limit - sets peak switch current to match system fault tolerance. |
| SYNC (Pin 7) | Mode control | GND = PFM/PWM auto-switching; VIN = forced PWM; external CMOS clock = synchronized operation (500–1000 kHz). |
| EN (Pin 8) | Enable control | Active-high logic input; <0.4 V disables device, reducing supply current to <1 µA for zero-power standby. |
| L (Pin 9) | Switch node | Connects to inductor; carries high di/dt switching current - requires short, wide trace and Kelvin connection to PGND. |
| PGND (Pin 10) | Power ground | Return path for high-current switch and inductor; must be solid copper plane tied to thermal pad for thermal and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated P-ch and N-ch MOSFETs eliminate external diode, reducing conduction loss and enabling >95% efficiency at full load. |
| Antiringing switch | Active only in fixed-output variants (including TPS62007) to suppress inductor ringing in DCM, lowering radiated EMI by >10 dBµV. |
| 100% duty cycle operation | Enables dropout as low as RDS(on) × IOUT - critical for maintaining 3.3 V output when input sags to 3.4 V in battery-depleted DSL modems. |
| Internal soft-start | ~1 ms voltage ramp prevents inrush current and output overshoot during hot-plug events or power-up sequencing. |
| Power-good comparator | Monitors regulated output with 2.5% hysteresis; provides reliable system reset signaling after valid voltage is established (>100 µs delay). |

FAQ
What is the output voltage configuration of the TPS62007DGSG4?
The TPS62007DGSG4 is a fixed-output variant delivering 3.3 V ±3% across its operating range. Unlike the adjustable TPS62000, it uses an internal resistor divider - the FB pin is not used and must remain unconnected. This eliminates external feedback components, reduces BOM count, and ensures factory-trimmed accuracy without calibration, making it ideal for high-volume DSL modem production where design simplicity and consistency are critical. The TPS62007DGSG4 maintains this output with ±0.6% load regulation and 0.05%/V line regulation.
How does the ILIM pin affect current limiting on the TPS62007DGSG4?
The ILIM pin on the TPS62007DGSG4 selects between two factory-characterized current limits: connecting ILIM to GND sets the typical switch current limit to 600 mA, while connecting it to VIN raises it to 1.2 A. This is implemented via internal logic that adjusts the current-sense threshold - not a simple resistor divider. For DSL modem applications drawing ≤600 mA, grounding ILIM ensures safe operation under short-circuit conditions without overdesigning the inductor or PCB traces. The TPS62007DGSG4's current limit remains stable across temperature due to on-die sensing.
Can the TPS62007DGSG4 operate with input voltage equal to its 3.3 V output?
Yes - the TPS62007DGSG4 supports 100% duty cycle operation, allowing it to maintain regulation when VIN approaches VOUT. When input drops to ~3.4 V, the high-side P-channel MOSFET remains continuously on, and output equals VIN minus the P-ch RDS(on) × IOUT drop (typically <100 mV at 300 mA). This dropout behavior is explicitly characterized in the datasheet and enables reliable operation during battery sag in handheld DSL modems. The TPS62007DGSG4 sustains this mode down to VIN = 2 V, though output accuracy degrades below 2.7 V due to reference limitations.
What is the purpose of the FC pin on the TPS62007DGSG4?
The FC (Filter Capacitor) pin on the TPS62007DGSG4 is a dedicated high-frequency input bypass node, distinct from VIN. It must be connected to a 0.1 µF ceramic capacitor placed as close as possible to the pin and tied directly to VIN. This capacitor filters switching noise injected into the input rail by the internal power stage, preventing coupling into sensitive analog sections or upstream regulators. Unlike standard input capacitors, FC serves a specific noise-suppression role - omitting it or misplacing the capacitor degrades EMI performance and may cause instability. The TPS62007DGSG4's FC pin is not a power supply input and must never be connected to an external voltage source.
Does the TPS62007DGSG4 require external compensation components?
No - the TPS62007DGSG4 features fully internal compensation, eliminating the need for external RC networks or type-II/type-III compensators. Its current-mode control architecture and factory-tuned transconductance amplifier provide stable loop response across all operating conditions (2–5.5 V input, 0–600 mA load, –40°C to 85°C). This simplifies layout, reduces BOM cost, and accelerates design validation. The TPS62007DGSG4 achieves phase margin >45° and gain margin >10 dB without any user-adjustable components - a key advantage over voltage-mode buck controllers requiring careful compensation design.
