Texas Instruments TPS62060DSGR

Overview

TPS62060DSGR from Texas Instruments is a synchronous step-down DC-DC converter optimized for single-cell Li-Ion, 3.3-V, and 5-V supply rails. It delivers up to 1.6 A output current with adjustable output voltage (0.8 V to VIN), operates at 3 MHz fixed PWM or auto PFM/PWM mode, achieves up to 97% efficiency at 4.2 V_IN/3.3 V_OUT, and supports 100% duty cycle for ultra-low dropout in battery-depleted conditions - used in portable media players for core voltage regulation.

For engineers reviewing the TPS62060DSGR datasheet, TPS62060DSGR pinout, TPS62060DSGR application, or TPS62060DSGR equivalent, key selection criteria include its 2-mm × 2-mm WSON-8 PowerPAD™ package, 18-µA quiescent current in PFM mode, ±1.5% output voltage accuracy in PWM mode, internal discharge resistor (75–1450 Ω), and thermal shutdown at 150°C with 10°C hysteresis.

Technical Context

The TPS62060DSGR implements voltage-mode control with input voltage feed-forward, enabling fast line/load transient response using small ceramic capacitors. Its dual-mode operation - forced 3-MHz PWM (MODE = high) or automatic PFM/PWM transition (MODE = low) - optimizes efficiency across 0–1.6 A load range while maintaining <1% output voltage ripple in PFM mode via dynamic voltage positioning.

Internally, it integrates high-side (95–150 mΩ at 5 V_IN) and low-side (75–100 mΩ) MOSFETs, a 0.6-V reference, undervoltage lockout (1.78 V fall / 1.95 V rise), soft-start (500 µs to 95% V_OUT), and clock dithering (±6 ns) to suppress EMI. The SW pin drives an external 1-µH inductor, while FB accepts resistive feedback for output adjustment.

Key Specifications

Pinout & Package

TPS62060DSGR uses an 8-pin WSON (DSG) package measuring 2.00 mm × 2.00 mm × 0.75 mm with exposed PowerPAD™ for thermal dissipation. The PowerPAD must be soldered to PCB ground plane to achieve R_θJA = 64.68°C/W.

FAQ

What is the recommended input capacitor for TPS62060DSGR?

The TPS62060DSGR datasheet specifies a 10-µF, 0603-size X5R/X7R ceramic capacitor placed as close as possible to the PVIN and AVIN pins. This value ensures stable operation across the 2.7–6 V input range and suppresses high-frequency switching noise. Larger values (e.g., 22 µF) may improve ripple but offer diminishing returns due to ESL limitations of small-case ceramics. The TPS62060DSGR does not require bulk electrolytic input capacitance.

How does the MODE pin affect efficiency and noise in TPS62060DSGR?

When MODE = low, the TPS62060DSGR enters auto PFM/PWM mode, achieving >85% efficiency at 1 mA load with 18-µA quiescent current - ideal for standby. When MODE = high, it forces fixed 3-MHz PWM, raising light-load efficiency by ~15% but increasing conducted EMI; clock dithering reduces peak harmonics by 10 dB. Engineers select MODE state based on system noise budget versus battery life trade-offs in the final TPS62060DSGR design.

Can TPS62060DSGR regulate output voltage below 0.8 V?

No. The TPS62060DSGR's internal 0.6-V reference and FB architecture limit the minimum adjustable output to 0.8 V, calculated as V_OUT = 0.6 V × (1 + R1/R2). Lower voltages would require external reference injection or a different converter family (e.g., TPS621xx series with 0.5-V reference). Attempting sub-0.8-V operation risks regulation loss and violates the TPS62060DSGR's specified operating conditions per Section 7.3 of the datasheet.

What is the purpose of the feed-forward capacitor (Cff) in TPS62060DSGR designs?

The 22-pF feed-forward capacitor (Cff) connected from FB to SW in the TPS62060DSGR schematic places a zero in the control loop to counteract the LC filter double pole, ensuring stability with 1-µH inductors and 10-µF output caps. Without Cff, phase margin drops below 45°, causing ringing or oscillation under load transients. Its value is derived from R1 and the desired zero frequency (25 kHz), and omitting it compromises the TPS62060DSGR's specified 50-µs transient response.

Does TPS62060DSGR support output capacitor discharge during shutdown?

Yes. When EN is pulled low, the TPS62060DSGR activates an internal discharge resistor (75–1450 Ω) between SW and PGND, actively discharging the output capacitor. This feature ensures V_OUT falls below 0.5 V within 10 ms for a 10-µF capacitor, preventing latch-up in downstream logic and meeting IEC 62368-1 safe discharge requirements. The resistor value varies with input voltage to maintain consistent discharge time across the 2.7–6 V range.
