Product details
Overview
TPS650001RTER from Texas Instruments is a highly integrated power management IC (PMIC) combining a 600-mA step-down DC-DC converter, two fixed-output LDO regulators (VLDO1 = 3.3 V, VLDO2 = 1.8 V), and spread-spectrum clock generation for EMI reduction. It operates from 2.3 V to 6 V input, supports automatic PFM/PWM mode transition via MODE pin, and delivers power-good monitoring for sequencing in portable electronics.
For engineers reviewing the TPS650001RTER datasheet, TPS650001RTER pinout, TPS650001RTER application, or TPS650001RTER equivalent, key selection criteria include its 20-pin WQFN package, fixed 1.2-V DC-DC output (per device option table), dual 300-mA LDOs with independent enables, 2.25-MHz switching frequency, and absence of supply voltage supervisor (SVS) - distinguishing it from TPS65001.
Technical Context
The TPS650001RTER implements a synchronous buck converter with internal high-side/low-side MOSFETs (RDS(on) = 240 mΩ / 185 mΩ), fixed 1.2-V output set by internal feedback (VREF = 0.6 V), and programmable PFM/PWM operation via MODE pin. Its oscillator integrates spread-spectrum modulation to reduce conducted EMI without external components.
Two independent LDOs accept separate inputs (VINLDO1/VINLDO2), each delivering 300 mA at fixed outputs (3.3 V and 1.8 V), with dropout voltage ≤370 mV at full load. Power-good (PG) is an open-drain output asserting low only when all enabled rails are in regulation - requiring explicit enable control of EN_DCDC, EN_LDO1, and EN_LDO2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DC-DC Output | Fixed 1.2 V - eliminates external feedback resistors; optimized for core logic or memory supply. |
| LDO1 Output | Fixed 3.3 V / 300 mA - suitable for I/O interfaces or analog peripherals without adjustment circuitry. |
| LDO2 Output | Fixed 1.8 V / 300 mA - matches common digital core voltages; supports low-power microcontrollers. |
| Switching Frequency | 2.25 MHz (typ) - enables use of compact 2.2-μH inductors and 10-μF ceramic output capacitors. |
| Input Voltage Range | 2.3 V to 6 V - compatible with single-cell Li-ion (2.7–4.2 V), Li-polymer, or dual-cell alkaline batteries. |
| Quiescent Current | 24–37 μA (TPS650001 family) - ensures ultra-low standby power in always-on portable systems. |
| Thermal Resistance | RθJA = 46.2 °C/W - requires thermal pad soldering for reliable 600-mA DC-DC operation at 85°C ambient. |
Pinout & Package
TPS650001RTER is housed in a 3.0 mm × 3.0 mm, 20-pin WQFN package (RUK) with exposed thermal pad. Pin numbering follows standard top-view orientation; thermal pad must be soldered to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 MR | Active-low manual reset input | Requires external pull-up; triggers system reset when asserted - unused in TPS650001 (no SVS). |
| 2 TRST | Reset timer capacitor connection | No function in TPS650001 - reserved pin; leave unconnected or float. |
| 3 PG | Open-drain power-good output | Pulled low only if EN_DCDC, EN_LDO1, and EN_LDO2 are high AND all outputs are in regulation. |
| 4 EN_LDO2 | Enable input for LDO2 | Active-high; controls 1.8-V rail independently - enables flexible power sequencing. |
| 5 EN_LDO1 | Enable input for LDO1 | Active-high; controls 3.3-V rail independently - allows staggered startup or dynamic shutdown. |
| 6 PGND | Power ground | Must connect directly to thermal pad and low-impedance ground plane; separates power return paths. |
| 7 SW | Switch node | Connects to inductor; carries high di/dt switching current - requires tight layout with minimal loop area. |
| 8 VINDCDC | DC-DC input supply | Main input for buck converter and internal control blocks; requires 10-μF local ceramic decoupling. |
| 9 MODE | Mode selection | High = forced PWM; Low = automatic PFM/PWM transition - critical for efficiency vs. noise trade-off. |
| 10 EN_DCDC | Enable input for DC-DC | Active-high; enables 1.2-V buck output - must be asserted before PG becomes valid. |
| 11 FB_DCDC | DC-DC feedback input | Internally tied to 0.6-V reference - no external resistor needed for fixed 1.2-V output. |
| 12 AGND | Analog ground | Reference for FB pins and internal bandgap; connect to PGND at single point near IC. |
| 13 FB_LDO1 | LDO1 feedback input | Internally configured for 3.3-V fixed output - no external components required. |
| 14 FB_LDO2 | LDO2 feedback input | Internally configured for 1.8-V fixed output - eliminates external resistor network. |
| 15 VINLDO1 | LDO1 input supply | Accepts 1.6–6 V; may be sourced from battery or DC-DC output - enables flexible rail partitioning. |
| 16 VLDO1 | LDO1 output | 3.3-V regulated output; capable of 300-mA continuous load with ≤370-mV dropout at full current. |
| 17 VLDO2 | LDO2 output | 1.8-V regulated output; same current and dropout specs as VLDO1 - ideal for dual-voltage SoCs. |
| 18 VINLDO2 | LDO2 input supply | Independent input path; allows different source than VINLDO1 - supports multi-rail battery architectures. |
| 19 RSTSNS | Reset sense input | No SVS function in TPS650001 - leave unconnected; not used for voltage monitoring. |
| 20 RST | Reset output | No SVS function in TPS650001 - remains inactive; open-drain output must not be pulled up. |
Key Features
| Feature | Design Value |
|---|---|
| Spread-spectrum clock generation | Reduces peak EMI by modulating 2.25-MHz switching frequency - eliminates need for external EMI filters. |
| Fixed-output LDO architecture | Removes external feedback resistors for VLDO1 (3.3 V) and VLDO2 (1.8 V), saving board space and BOM cost. |
| Automatic PFM/PWM mode transition | Maintains >85% efficiency from 100 μA to 600 mA load - extends battery life across sleep and active states. |
| Independent LDO enables | EN_LDO1 and EN_LDO2 allow per-rail power control - essential for low-power state management in embedded systems. |
| Integrated power-good monitoring | Single open-drain PG pin reports combined status of DC-DC + both LDOs - simplifies system-level sequencing logic. |

FAQ
What is the DC-DC output voltage of the TPS650001RTER?
The TPS650001RTER features a fixed 1.2-V DC-DC output voltage, internally set by a 0.6-V reference and 1:2 resistor divider - eliminating the need for external feedback components. This output is optimized for powering processor cores or memory subsystems in portable devices, and its value is confirmed in the Device Options table of the SLVS810C datasheet.
Does the TPS650001RTER include a supply voltage supervisor (SVS)?
No, the TPS650001RTER does not include a supply voltage supervisor. Per the Device Options table in SLVS810C, SVS is marked "N/A" for TPS650001, distinguishing it from TPS65001 and TPS650061. Pins MR, TRST, RSTSNS, and RST are present but nonfunctional - they must be left unconnected or floated in the layout.
What are the fixed output voltages of the LDOs in the TPS650001RTER?
The TPS650001RTER integrates two fixed-output LDO regulators: VLDO1 delivers 3.3 V at up to 300 mA, and VLDO2 delivers 1.8 V at up to 300 mA. These values are factory-programmed and require no external feedback resistors, as confirmed in the Device Options section and Pin Functions table of the SLVS810C datasheet.
How does the MODE pin affect operation of the TPS650001RTER?
The MODE pin on the TPS650001RTER selects between two operating modes: pulling MODE high forces continuous PWM operation for lowest output ripple, while pulling MODE low enables automatic PFM/PWM transition to maximize light-load efficiency. This behavior is documented in Section 9.1 (Overview) and Figure 12 (PFM to PWM Transition) of SLVS810C.
What package type and pin count does the TPS650001RTER use?
The TPS650001RTER uses a 20-pin WQFN package (RUK variant) with 3.0 mm × 3.0 mm body size and exposed thermal pad. This is explicitly stated in the Device Information table and Pin Configuration section of SLVS810C, and differs from the 16-pin RTE package used by TPS65000.
