TPS60150 5-V, 140-mA Charge-Pump
1 Features
3 Description
•
•
•
•
•
The TPS60150 device is a switched capacitor voltage
converter that produces a regulated, low noise, and
low-ripple output voltage of 5 V from an unregulated
input voltage.

2.7-V to 5.5-V Input Voltage Range
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)
X2 Charge Pump
Hardware Enable and Disable Function
Built-in Soft Start
Built-in Undervoltage Lockout Protection
Thermal and Overcurrent Protection
Available in a 2-mm × 2-mm 6-Pin SON Package
with 0.8-mm Height
The TPS60150 device operates in skip mode when
the load current falls less than 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, therefore saving PCB space.
Inrush current is limited by the soft-start function
during power on and power transient states.
The TPS60150 device operates over a free-air
temperature range of –40°C to 85°C. The device is
available with a small 2-mm × 2-mm 6-pin SON
package (QFN).

7.1 Overview
The TPS60150 regulated charge pump provides a regulated output voltage for various input voltages. The
TPS60150 device 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.

7.3 Feature Description
7.3.1 Enable
An enable pin on the regulator is used to place the device into an energy-saving shutdown mode. In this mode,
the output is disconnected from the input, and the input quiescent current is reduced to 10 μA maximum.
7.3.2 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.
7.3.3 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 reenabled. Continuously running the regulator into thermal shutdown can degrade reliability. The
regulator also provides current limit to protect itself and the load.

7.4 Device Functional Modes
7.4.1 Soft Start
An internal soft start limits the inrush current when the device is being enabled.
7.4.2 Normal Mode and Skip Mode Operation
The TPS60150 device has skip mode operation as shown in Figure 5. The TPS60150 device enters skip mode if
the output voltage reaches 5 V +0.1 V and the load current is less than 8 mA (typical). In skip mode, the
TPS60150 device disables the oscillator and decreases the prebias current of the output stage to reduce the
power consumption. Once the output voltage dips less than the threshold voltage of 5 V +0.1 V, the TPS60150
device begins switching to increase output voltage until the output reaches 5 V +0.1 V. When the output voltage
dips less than 5 V, the TPS60150 device returns to normal pulse width modulation (PWM) mode; thereby
reenabling the oscillator and increasing the prebias current of the output stage to supply output current.
The skip threshold voltage and current depend on input voltage and output current conditions.

7.4.3 Short Circuit Protection
The TPS60150 device has internal short circuit protection to protect the IC when the output is shorted to ground.
To avoid damage when output is shorted to ground, the short circuit protection circuitry senses output voltage
and clamps the maximum output current to 80 mA (typical).

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. 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.
8.1 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 through USB On-the-Go (OTG). As Figure 7 shows, the USB OTG circuitry in
the portable device requires a 5-V power rail and up to 140 mA of current. The TPS60150 device may be used to
provide a 5-V power rail in a battery powered system.

8.2.1.1 Design Requirements
The design guideline provides a component selection to operate the device within the Recommended Operating
Conditions.
8.2.1.2 Detailed Design Procedure
8.2.1.2.1 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 CF, respectively) should also be surface-mount ceramic types.

If ILOAD = 140 mA, f = 1.5 MHZ, and ΔVCFLY = 100 mV, the minimum value of the flying capacitor should be 1 μF.

The minimum output capacitance for all output levels is 2.2 μF due to control stability. Larger ceramic capacitors

9 Power Supply Recommendations
The TPS60150 device has no special requirements for its input power supply. The input power supply's output
current must be rated according to the supply voltage, output voltage and output current of the TPS60150
device.
10 Layout
10.1 Layout Guidelines
Large transient currents flow in the VIN, VOUT, and GND traces. To minimize both input and output ripple, keep
the capacitors as close as possible to the regulator using short, direct circuit traces.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
