Product details
Overview
TPS60151DRVT from Texas Instruments is a regulated X2 charge pump DC-DC converter that generates a stable 5-V output from an input range of 2.7 V to 5.5 V, delivering up to 140 mA at 5 V with 1.5-MHz switching frequency and built-in reverse current protection - ideal for USB OTG power rail generation in portable devices.
For engineers reviewing the TPS60151DRVT datasheet, TPS60151DRVT pinout, TPS60151DRVT application, or TPS60151DRVT equivalent, key selection criteria include its 2-mm × 2-mm WSON-6 package, skip-mode quiescent current of 90 μA, hardware enable control, soft-start functionality, and compliance with HDMI/USB OTG power requirements.
Technical Context
The TPS60151DRVT uses an X2 charge pump topology with internal FETs (Q1–Q4) driven by a 1.5-MHz clock to regulate VOUT at 5 V by controlling the flying capacitor voltage at 2.5 V and compensating for FET drops. It operates in two phases: charging CF to 2.5 V (Q2/Q3 on), then discharging CF into VOUT (Q1/Q4 on).
It features dual operating modes: normal PWM mode above ~8 mA load, and skip mode below that threshold - disabling the oscillator and reducing pre-bias current to achieve 90-μA no-load quiescent current. Protection includes undervoltage lockout (2.1 V threshold), thermal shutdown (160°C trip), overcurrent limiting (500 mA), and short-circuit current clamping (80 mA typical).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion, Li-polymer, and multi-cell alkaline/NiMH battery inputs without external regulation. |
| Output Voltage | 5.0 V ±2% (4.8–5.2 V) - tightly regulated for USB OTG and HDMI VBUS compliance. |
| Max Output Current | 140 mA at VIN > 3.3 V - sufficient to power USB OTG transceivers and HDMI sink-side 5-V supply. |
| Switching Frequency | 1.5 MHz - enables use of small 1-μF flying and 2.2-μF input/output ceramic capacitors, minimizing PCB area. |
| Quiescent Current | 90 μA in skip mode - extends battery life in standby states of portable instrumentation and handheld meters. |
| Protection Features | Reverse current blocking, UVLO (2.1 V), thermal shutdown (160°C), and short-circuit current limit (80 mA) - ensures robust operation in unregulated battery systems. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and consumer portable equipment environments. |
Pinout & Package
TPS60151DRVT is housed in a thermally enhanced 2-mm × 2-mm, 0.8-mm height, 6-pin WSON (DRV) package with exposed thermal pad - optimized for compact, high-density portable PCB layouts and efficient heat dissipation in space-constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for all internal circuits and external capacitors; must be low-impedance connection to system ground plane. |
| VIN | Power input | Accepts 2.7–5.5 V unregulated supply; connects to 2.2-μF input capacitor (C1) placed adjacent to pin. |
| VOUT | Regulated output | Delivers 5-V output; connects to 2.2-μF output capacitor (C3); reverse-current protected to prevent backfeed into source. |
| CP+ | Flying capacitor terminal (+) | Connects to one side of 1-μF flying capacitor (C2); forms charge-transfer node during discharge phase. |
| CP− | Flying capacitor terminal (−) | Connects to other side of C2; forms charge-transfer node during charging phase; referenced to GND during CP+ charging. |
| ENA | Enable control input | Active-high logic input (VIH ≥1.3 V); pulls to GND to disable device and reduce IQ to ≤10 μA; internal pull-down not present. |
Key Features
| Feature | Design Value |
|---|---|
| X2 charge pump architecture | Doubles input voltage internally to generate precise 5-V output even when VIN exceeds 5 V - eliminates need for inductor-based buck-boost solutions. |
| Hardware enable/disable | Digital ENA pin allows system-level power sequencing and dynamic power gating - critical for USB OTG host negotiation and low-power sleep modes. |
| Built-in soft start | 150-μs ramp time limits inrush current during power-up - prevents input rail droop and avoids false triggering of system brownout detectors. |
| Output reverse current protection | Blocks current flow from VOUT to VIN when ENA = low or VIN is absent - mandatory for HDMI and USB OTG to avoid draining connected peripherals. |
| Skip mode operation | Automatically disables switching below ~8 mA load to reduce IQ to 90 μA - improves light-load efficiency by >30% versus fixed-frequency operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar charge pump regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60150DRVT | Identical pinout and electrical specs, but lacks ENA pin - always-on operation only. | No hardware enable control; unsuitable for systems requiring dynamic power gating or USB OTG host negotiation. | Select TPS60150DRVT only if continuous operation is acceptable and board layout cannot accommodate ENA routing. |
| MAX1516ETA+ | 5-V fixed-output charge pump, 120-mA max, 1-MHz switching, different pinout (8-pin μMAX), no reverse current protection. | Higher quiescent current (120 μA), no reverse-blocking - requires external diode for HDMI/OTG use. | Choose MAX1516ETA+ only if footprint flexibility exists and external protection components are acceptable for cost-sensitive designs. |
Compared with TPS60151DRVT, TPS60150DRVT removes enable control but retains identical regulation and efficiency; MAX1516ETA+ offers lower max current and no integrated reverse protection - making TPS60151DRVT the only option supporting full USB OTG/HDMI compliance with zero external components.

FAQ
What is the minimum input voltage required for TPS60151DRVT to regulate 5 V?
The TPS60151DRVT maintains 5-V regulation down to 2.7 V input. Below this threshold, undervoltage lockout activates at 2.1 V (typical), disabling the device. At VIN = 2.7 V, it delivers up to 50 mA; full 140-mA capability requires VIN > 3.3 V per datasheet Section 7.5.
Does TPS60151DRVT support reverse current blocking when disabled?
Yes, TPS60151DRVT provides active reverse current protection on the VOUT pin regardless of ENA state. When ENA = low or VIN is removed, internal circuitry blocks current flow from VOUT back to VIN - a key feature verified in Figure 6 of the datasheet for HDMI and USB OTG applications.
How many external capacitors does TPS60151DRVT require for basic operation?
The TPS60151DRVT requires exactly three external capacitors: a 2.2-μF input capacitor (C1), a 2.2-μF output capacitor (C3), and a 1.0-μF flying capacitor (C2). All must be ceramic X5R/X7R types in 0603 package per Section 9.2.2.1 - no additional compensation or bypass caps are needed.
What is the purpose of the CP+ and CP− pins on TPS60151DRVT?
The CP+ and CP− pins connect to opposite terminals of the flying capacitor (C2). During the first half-cycle, CP− is grounded and CP+ charges C2 to 2.5 V; during the second half-cycle, CP+ connects to VOUT and CP− connects to VIN, transferring stored charge to the output - enabling X2 voltage doubling without inductors.
Can TPS60151DRVT be used to drive white LEDs directly?
Yes, TPS60151DRVT can drive parallel white LEDs with ballast resistors, as shown in Figure 26 of the datasheet. Its 5-V output and 140-mA capability support multiple standard WLEDs (VF ≈ 3.0–3.6 V), though LED current regulation is resistor-based - not constant-current, so brightness varies with input voltage and temperature.
