Product details

Overview

TPS650531RGET from Texas Instruments is a 5-channel power management IC integrating two synchronous step-down converters (DCDC1: 1 A, DCDC2: 1 A) and three low-dropout regulators (VLDO1: 400 mA, VLDO2/VLDO3: 200 mA each), designed for single-cell Li-Ion/Li-Polymer powered systems such as OMAP™-based handhelds and portable media players. It operates at 2.25 MHz fixed frequency with PFM/PWM auto-mode switching, ±1% output voltage accuracy in PWM mode, and supports externally adjustable DC-DC outputs and LDO1/LDO2.

For engineers reviewing the TPS650531RGET datasheet, TPS650531RGET pinout, TPS650531RGET application, or TPS650531RGET equivalent, key selection criteria include dual 1-A DC-DC converter capability, 1.5–6.5 V LDO input range, 180° out-of-phase operation to reduce input RMS current, and support for dynamic voltage scaling via MODE and DEF pins in battery-constrained embedded designs.

Technical Context

The TPS650531RGET implements a voltage-mode PWM controller with input voltage feed-forward for fast line/load regulation and uses internal P-channel (280–630 mΩ) and N-channel (220–450 mΩ) MOSFETs per DC-DC stage. Its 180° phase shift between DCDC1 and DCDC2 minimizes input capacitor RMS current, enabling compact 22-μF ceramic input capacitance.

Power Save Mode automatically engages below ~I_IN/32 Ω threshold (e.g., ~113 μA at 3.6 V), reducing quiescent current to 32 μA total for both converters. Forced PWM mode is activated by pulling MODE high, ensuring fixed-frequency operation for noise-sensitive applications.

Key Specifications

Parameter	Value and Actual Design Meaning
DCDC1 Output Current	1 A - supports I/O rail supply for processors requiring up to 1 A at 0.6–V_IN adjustable output

EN_LDO2 (Pin 11)	LDO2 enable input	Independent active-high control for 200-mA LDO powering auxiliary rails
MODE (Pin 23)	Operating mode select	Low = auto PFM/PWM; high = forced PWM - critical for EMI-controlled layouts
RESET (Pin 10)	Open-drain reset output	Active-low with 100-ms delay; asserts after undervoltage (V_CC < 1.8 V) or thermal shutdown

Key Features

Feature	Design Value
180° out-of-phase DC-DC operation	Reduces input capacitor RMS current by ~30%, allowing smaller 22-μF ceramic input caps
Integrated P/N-MOSFET power stages	Eliminates external high-side/low-side switches; typical r_DS(on) = 280 mΩ (P) / 220 mΩ (N) at 3.6 V
Dynamic voltage scaling support	DEF_DCDC2 (Pin 5) selects 1.2 V / 1.8 V for DCDC2; DEF_LDO (Pin 4) selects 1.2 V / 1.3 V for VLDO3
Internal LDO discharge paths	350-Ω pull-down on VLDO1/VLDO2/VLDO3 when disabled - prevents floating outputs during sequencing
Thermal shutdown with hysteresis	Triggers at 150°C junction; releases at 130°C - protects against sustained overload or poor heatsinking

FAQ

What is the maximum output current capability of the DCDC2 converter in the TPS650531RGET?

The TPS650531RGET supports a maximum continuous output current of 1 A from its DCDC2 converter, which is designated for core voltage supply in processor-based systems. This is confirmed in the Features section of the SLVS754D datasheet and distinguishes it from the TPS65053RGET (600 mA) and TPS650532RGET (also 1 A). The 1-A rating applies across the full input voltage range (2.5–6 V) and ambient temperature (–40°C to 85°C).

Does the TPS650531RGET support dynamic voltage scaling for the DCDC2 output?

Yes, the TPS650531RGET supports dynamic voltage scaling for DCDC2 via the DEF_DCDC2 pin (Pin 5). When this pin is driven high, DCDC2 outputs 1.8 V; when low, it outputs 1.2 V. This feature enables real-time adjustment of processor core voltage during different operating modes, improving power efficiency in OMAP™ and DSP applications. The TPS650531RGET datasheet explicitly confirms this behavior in the Pin Functions table.

What is the output voltage of VLDO3 on the TPS650531RGET?

The VLDO3 output voltage on the TPS650531RGET is fixed at 1.2 V, as specified in the Recommended Operating Conditions table (Section 6.3) of the SLVS754D datasheet. This differs from the TPS65053RGET (1.3 V) and TPS650532RGET (1.5 V), making the TPS650531RGET the correct choice when a 1.2-V auxiliary rail is required for interfaces such as LPDDR or specific sensor ICs.

How does the MODE pin affect the operation of the TPS650531RGET?

The MODE pin (Pin 23) on the TPS650531RGET selects between automatic Power Save Mode (PFM at light load, PWM at heavy load) when pulled low, and forced fixed-frequency PWM operation when pulled high. Forced PWM eliminates frequency variation for EMI-sensitive designs, while Power Save Mode reduces quiescent current to 32 μA total for both DC-DC converters - a key battery-life optimization confirmed in Section 6.6 Electrical Characteristics.

What package type and thermal characteristics apply to the TPS650531RGET?

The TPS650531RGET is packaged in a VQFN-24 (RGE) package measuring 4.00 mm × 4.00 mm with 0.5-mm pitch and an exposed thermal pad (PowerPAD™). Its junction-to-ambient thermal resistance (R_θJA) is 31.4°C/W on a standard JEDEC high-K test board, and the recommended PCB layout requires soldering the PowerPAD™ to a solid ground plane to achieve rated 1-A DC-DC performance without thermal derating.
