Product details
Overview
TPS65053 from Texas Instruments is a 5-channel power management IC integrating two synchronous step-down converters (DCDC1: 1 A, DCDC2: 600 mA) and three low-dropout regulators (VLDO1: 400 mA, VLDO2/VLDO3: 200 mA each), designed for single-cell Li-Ion/Li-Polymer powered portable systems including OMAP™ processors and low-power DSPs. It operates from 2.5 V to 6 V input, delivers ±1% output voltage accuracy in PWM mode, and supports 2.25 MHz fixed-frequency or light-load PFM operation.
For engineers reviewing the TPS65053 datasheet, TPS65053 pinout, TPS65053 application, or TPS65053 equivalent, key selection considerations include its dual-phase 180° out-of-phase DC-DC architecture for reduced input RMS current, externally adjustable output voltages via FB pins, integrated 32-μA quiescent current operation, and support for dynamic voltage scaling in core/I/O rail configurations.
Technical Context
The TPS65053 employs voltage-mode control 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 converter. Its 2.25 MHz switching frequency enables compact 2.2 μH inductors and ceramic capacitors (e.g., 22 μF input, 10–22 μF output).
Two DC-DC converters operate synchronously with 180° phase shift to minimize input ripple; MODE pin selects between automatic PFM/PWM transition or forced PWM. LDOs feature 280 mV dropout at full load, 1 V feedback reference, and internal discharge resistors (350 Ω) for fast turn-off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DCDC1 Output Current | 1 A - supports I/O rail supply for processors requiring stable high-current 3.3 V or adjustable voltage |
| DCDC2 Output Current | 600 mA - powers core voltage rails such as 1.2–1.5 V for OMAP™/DSP applications |
| LDO1 Output Current | 400 mA - delivers regulated auxiliary power for memory, interfaces, or analog circuitry |
| LDO2/LDO3 Output Current | 200 mA each - supplies low-noise bias for sensors, RF sections, or peripheral logic |
| Switching Frequency | 2.25 MHz ±10% - enables use of small 2.2 μH inductors and minimizes EMI filtering requirements |
| Quiescent Current | 32 μA total (both DC-DCs active, no load, PFM mode) - extends battery life in standby/sleep states |
| Output Voltage Accuracy | ±1% in PWM mode - ensures tight regulation for sensitive digital core and I/O domains |

| EN_LDO3 (Pin 12) | Enable input | Active-high control for second 200 mA LDO; isolates auxiliary supplies during sleep |
| L1 (Pin 17) | Switch node | Connects to inductor for DCDC1; requires low-inductance layout to minimize switching losses |
| L2 (Pin 15) | Switch node | Connects to inductor for DCDC2; phase-shifted relative to L1 to reduce input ripple |
| PGND1 (Pin 18) | Power ground | Return path for DCDC1 high-side/low-side MOSFETs; must be routed separately from AGND |
| PGND2 (Pin 14) | Power ground | Return path for DCDC2 high-side/low-side MOSFETs; avoids coupling into analog sections |
| AGND (Pin 24) | Analog ground | Reference for FB pins, MODE, RESET, and LDO feedback; connects to PGND and PowerPAD™ |
| VINLDO1 (Pin 2) | LDO1 input | Accepts 1.5–6.5 V; may be supplied from battery or DCDC1 output for cascaded regulation |
| VINLDO2/3 (Pin 8) | LDO2/LDO3 input | Shared input for both 200 mA LDOs; simplifies layout when sourced from common rail |

| MODE (Pin 23) | Operating mode select | Pull high for forced PWM; pull low for automatic PFM/PWM transition based on load |
| RESET (Pin 10) | Open-drain reset output | Active-low with 100 ms delay; asserts after power stabilization or THRESHOLD pin violation |
| THRESHOLD (Pin 5) | Reset threshold input | Monitors system voltage; falling edge below 1.0 V triggers 100 ms reset pulse on RESET pin |
| VCC (Pin 1) | Internal bias supply | Must connect to same rail as VINDCDC1/2; powers internal logic, gate drivers, and LDO controllers |
| VINDCDC1/2 (Pin 16) | DC-DC input supply | Primary input for both converters (2.5–6 V); shared rail reduces component count and layout area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-rail power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS650531 | DCDC2 rated at 1 A (vs. 600 mA); VLDO3 = 1.2 V (vs. 1.3 V) | Better suited for higher-core-current processors like OMAP-4430 where 1 A core rail is required | Select TPS650531 if core load exceeds 600 mA; verify VLDO3 voltage compatibility with target sensor/analog ICs |
| TPS65058 | DCDC1 fixed at 3.3 V; DCDC2 selectable 1.2/1.8 V; VLDO1 = 3.3 V (non-adjustable) | Optimized for fixed-voltage systems with dynamic core scaling but no need for adjustable I/O rail | Choose TPS65058 when I/O voltage is fixed and board space is constrained-eliminates FB resistors and saves 2 passives |
Compared with TPS650531 and TPS65058, the TPS65053 offers full external adjustability for all DC-DC outputs and LDO1/LDO2, making it ideal for prototyping and multi-platform designs where voltage flexibility outweighs fixed-feature optimization.

FAQ
What is the maximum output current capability of each regulator in the TPS65053?
The TPS65053 provides 1 A from DCDC1 (I/O rail), 600 mA from DCDC2 (core rail), 400 mA from VLDO1, and 200 mA each from VLDO2 and VLDO3. These values are specified under recommended operating conditions with proper thermal management and input voltage ≥2.5 V. Exceeding these currents may trigger thermal shutdown or reduce output voltage accuracy.
How does the MODE pin affect the operation of the TPS65053?
The MODE pin on the TPS65053 selects between automatic PFM/PWM mode (MODE = GND) and forced PWM mode (MODE = high). In PFM mode, the device achieves ultra-low quiescent current (32 μA) at light loads; in forced PWM, it maintains constant 2.25 MHz switching for predictable EMI and improved transient response, though quiescent current rises to ~1.25 mA.
Can the TPS65053 support dynamic voltage scaling (DVS) for processor core voltage?
Yes-the TPS65053 supports DVS for core voltage via external resistor networks on FB_DCDC2 and optional GPIO control of the MODE pin. While the TPS65053 itself lacks built-in voltage selection pins like DEF_DCDC2 (present on TPS650531/TPS650532), its fully adjustable FB interface allows software-controlled DAC or resistor-switching circuits to reconfigure DCDC2 output dynamically during runtime.
What is the purpose of the THRESHOLD and RESET pins on the TPS65053?
The THRESHOLD pin monitors an external voltage rail; when it falls below 1.0 V (typical), the TPS65053 asserts an active-low RESET signal with 100 ms delay. This provides reliable power-on reset and brownout detection. The open-drain RESET output can drive multiple downstream devices or microcontroller reset inputs, ensuring synchronized system initialization.
Is the TPS65053 compatible with ceramic output capacitors, and what are the recommended values?
Yes-the TPS65053 is fully compatible with ceramic output capacitors. Recommended values are 10–22 μF for DCDC1 and DCDC2 outputs, and 4.7 μF for VLDO1 and 2.2 μF for VLDO2/VLDO3. X5R/X7R dielectrics with ≤100 mΩ ESR are preferred to ensure stability and minimize output ripple in both PWM and PFM modes.
