It maintains 5-V regulation even when VIN is greater than 5 V. 1 • • • • • • • Input Voltage Range 2.7 V to 5.5 V Fixed Output Voltage of 5 V Maximum Output Current: 140 mA 1.5-MHz Switching Frequency Typical 90-μA Quiescent Current at No Load Condition (Skip Mode) Output Reverse Current Protection X2 Charge Pump Hardware Enable and Disable Function Built-in Soft Start Built-in Undervoltage Lockout Protection Thermal and Overcurrent Protection 2-mm × 2-mm 6-Pin SON-Package with 0.8-mm Height The TPS60151 has built-in current limit and output reverse current protection that are ideal for HDMI, USB OTG and other battery powered applications. TPS60151 operates in skip mode when the load current falls below 8 mA under typical condition. In skip mode operation, quiescent current is reduced to 90 μA. Only 3 external capacitors are needed to generate the output voltage, thereby saving PCB space. Inrush current is limited by the soft-start function during power on and power transient states. 2 Applications • • • • • • The 5-V output can supply a minimum of 140-mA current. USB On the Go (OTG) HDMI Portable Communication Devices PCMCIA Cards Mobile Phones, Smart Phones Handheld Meters The TPS60151 operates over a free air temperature range of –40°C to 85°C.

The TPS60151 regulates the voltage across the flying capacitor to 2.5 V and controls the voltage drop of Q1 and Q2 while a conversion clock with 50% duty cycle drives the FETs. VIN Q2 Q1 OFF ON 2.5V - + CF Q3 Q4 OFF ON VOUT COUT Figure 3. Charging Mode During the first half cycle, Q2 and Q3 transistors are turned on and flying capacitor, CF, will be charged to 2.5 V ideally. VIN Q1 Q2 OFF VQ1 ON 2.5V - + CF Q3 Q4 ON OFF VOUT COUT Figure 4. Discharging Mode During the second half cycle, Q1 and Q4 transistors are turned on. Capacitor CF will then be discharged to output. The output voltage can be calculated as follows: Vout = VIN – VQ1 + V(CF) - VQ4 = VIN – VQ1 + 2.5 V - VQ4 = 5 V. (Ideal) (1) The output voltage is regulated by output feedback and an internally compensated voltage control loop.

In this mode, the output is disconnected from the input and the input quiescent current is reduced to 10 μA maximum. 8.3.2 Output Reverse Current Protection Applications like HDMI or USB OTG generally do not tolerate output reverse current that can drain power from connected devices. Special considerations were put in place to prevent that from happening. Figure 5 is a testing circuit; and, Figure 6 shows reverse current protection test results under various conditions.

Reverse Current Test Results (Typical) 8.3.3 Undervoltage Lockout When the input voltage drops, the undervoltage lockout prevents misoperation by switching off the device. The converter starts operation again when the input voltage exceeds the threshold, provided the enable pin is high. 8.3.4 Thermal Shutdown Protection The regulator has thermal shutdown circuitry that protects it from damage caused by overload conditions. The thermal protection circuitry disables the output when the junction temperature reached approximately 160°C, allowing the device to cool. When the junction temperature cools to approximately 140°C, the output circuitry is automatically re-enabled. Continuously running the regulator into thermal shutdown can degrade reliability. The regulator also provides current limit to protect itself and the load. 8.4 Device Functional Modes 8.4.1 Soft Start An internal soft start limits the inrush current when the device is being enabled.

Normal Mode and Skip Mode Operation The TPS60151 has skip mode operation as shown in Figure 7. The TPS60151 enters skip mode if the output voltage reaches 5 V + 0.1 V and the load current is below 8 mA (typical). In skip mode, the TPS60151 disables the oscillator and decreases the pre-bias current of the output stage to reduce the power consumption. Once the output voltage dips below threshold voltage, 5 V + 0.1 V, the TPS60151 begins switching to increase output voltage until the output reaches 5 V + 0.1 V. When the output voltage dips below 5 V, the TPS60151 returns to normal pulse width modulation (PWM) mode; thereby re-enabling the oscillator and increasing the pre-bias current of the output stage to supply output current. The skip threshold voltage and current depend on input voltage and output current conditions. 8.4.3 Over-current Protection and Short-Circuit Protection The TPS60151 has internal short circuit protection to protect the IC when the output is over loaded or shorted to ground. Figure 8 illustrates the protection circuit. IP is directly related to IOUT and the maximum IP is clamped by IR3*k*n. The TPS60151 ensures a current limit of 500 mA or less which is mandated by the HDMI electrical specification. To further avoid damage when output is shorted to ground, the short circuit protection circuitry senses the output voltage and adjusts Vbias down to clamp the maximum output current to a lower value –80 mA (typical). 10 Submit Documentation Feedback Copyright © 2009–2019, Texas Instruments Incorporated Product Folder Links: TPS60151 TPS60151 www.ti.com SLVSA02B – SEPTEMBER 2009 – REVISED JANUARY 2019 Device Functional Modes (continued) Vmax 1 : k M10 M9 VIN M7 IR3 M3 M5 vbias Ip 1 : n M11 R3 VR3 Figure 8.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information Most of today’s battery-powered portable electronics allow and/or require data transfer with a PC. One of the fastest data transfer protocols is via USB OTG. As Figure 10 shows, the USB OTG circuitry in the portable device requires a 5-V power rail and up to 140mA of current. The HDMI specification calls for a 5-V power rail that can source 55mA or more current. The TPS60151 may be used to provide a 5-V power rail in a battery powered system. Alternatively, low-cost portable electronics with small LCD displays require a low-cost solution for providing the WLED backlight. As shown in Figure 26, the TPS60151 can also be used to drive several WLEDs in parallel, with the help of ballast resistors. 9.2 Typical Application Figure 10 shows USB OTG circuitry.

Application Circuit for OTG System 9.2.1 Design Requirements The design guideline provides a component selection to operate the device within the recommended operating conditions. 9.2.2 Detailed Design Procedure 9.2.2.1 Capacitor Selection For minimum output voltage ripple, the output capacitor (COUT) should be a surface-mount ceramic capacitor. Tantalum capacitors generally have a higher effective series resistance (ESR) and may contribute to higher output voltage ripple. Leaded capacitors also increase ripple due to the higher inductance of the package itself. To achieve the best operation with low input voltage and high load current, the input and flying capacitors (CIN and CFLY, respectively) should also be surface-mount ceramic types. 12 Submit Documentation Feedback Copyright © 2009–2019, Texas Instruments Incorporated Product Folder Links: TPS60151 TPS60151 www.ti.com SLVSA02B – SEPTEMBER 2009 – REVISED JANUARY 2019 Typical Application (continued) VIN VOUT (5 V) GND ENA VIN CP- VOUT COUT ENABLE /DISABLE CFLY CP+ CIN Figure 11.

Output capacitance, COUT, is also strongly related to output ripple voltage and loop stability, ILOAD(MAX) + 2I ´ ESRCOUT VOUT(RIPPLE) = (2 ´ f ´ COUT ) LOAD(MAX) (4) The minimum output capacitance for all output levels is 2.2 μF due to control stability. Larger ceramic capacitors or low ESR capacitors can be used to lower the output ripple voltage. Table 1.
