description
The TPS6031X step-up, regulated charge pumps
generate a 3-V ±4% or 3.3-V ±4% output voltage
from a 0.9-V to 1.8-V input voltage (one alkaline,
NiCd, or NiMH battery).
ACTUAL SIZE
3,05 mm x 4,98 mm
Only five small 1-µF ceramic capacitors are required to build a complete high-efficiency dc/dc charge pump
converter. To achieve the high efficiency over a wide input voltage range, the charge pump automatically selects
between a 3x or 4x conversion mode.

HIGH-EFFICIENCY CHARGE PUMP WITH SNOOZE MODE
SLVS362A – MAY 2001 – REVISED AUGUST 2001
description (continued)
Output 1 (OUT1) can deliver a maximum of 40 mA, from a 1-V input, with output 2 (OUT2) not loaded. OUT2
can deliver a maximum of 20 mA, from a 1-V input, with OUT1 not loaded. Both outputs can be loaded at the
same time, but the total output current of the first voltage doubler must not exceed 40 mA. For example, the load
at OUT1 is 20 mA and the load at output 2 is 10 mA.
In snooze mode, the devices operate with a typical operating current of 2 µA, while the output voltage is
maintained at 3.3 V ±10% or 3 V ±10%, respectively. This is lower than the self-discharge current of most
batteries. Load current in snooze mode is limited to 2 mA. If the load current increases above 2 mA, the output
voltage drops further and the devices automatically exits the snooze mode and operate in normal mode to
regulate to the nominal output voltage with higher output currents. The device is set into the snooze mode by
taking the SNOOZE pin low, and is set into normal operating mode by taking the SNOOZE pin high.
A power-good function supervises the output voltage of OUT2 and can be used for power up and power down
sequencing. Power-good (PG) is offered as either open-drain or push-pull output.

HIGH-EFFICIENCY CHARGE PUMP WITH SNOOZE MODE

detailed description
operating principle
The TPS6031X charge pumps are voltage quadruplers that provide a regulated 3.3-V or 3-V output from a 0.9-V
to 1.8-V input. They deliver a maximum load current of 20 mA. Designed specifically for space critical battery
powered applications, the complete converter requires only five external capacitors and enables the design to
use low-cost, small-sized, 1-µF ceramic capacitors. The TPS6031X circuits consist of an oscillator, a voltage
reference, an internal resistive feedback circuit, two error amplifiers, two charge pump stages with MOSFET
switches, a shutdown/start-up circuit, and a control circuit.
snooze mode
The devices contain a circuit which dramatically reduces the quiescent current at light loads. This so called
snooze mode must be enabled by pulling the SNOOZE pin low. When the output current decreases below the
snooze mode threshold, the device enters the snooze mode. In snooze mode, the main error amplifier with 4%
error and 50-µA supply current is disabled and a 10%, 2-µA regulator controls the output voltage.
start-up procedure
The start-up performance of the device is independent of the level of the snooze input. When voltage is applied
to the input, CP1 will first enter a dc start-up mode during which the capacitor on OUT1 is charged up to about
VIN. After that, it starts switching to boost the voltage further up to about two times VIN. CP1 first enters a dc
start-up mode during which the capacitor on OUT1 is charged up to about VIN. CP2 then follows and charges
up the capacitor on OUT2 to about the voltage on OUT1, after that, it also starts switching and boosts up the
voltage to its nominal value. The voltage at the SNOOZE pin must not exceed the highest voltage applied to
the device.
NOTE:
During start-up with VOUT = 0 V, the highest voltage is the input voltage.
power-good detector
The power-good output is an open-drain output on the TPS60310 and TPS60311 or a push-pull output on the
TPS60312 and TPS60313. The PG-output pulls low when the output of OUT2 is out of regulation. When the
output rises to within 98% of regulation, the power-good output goes active high. In shutdown, power-good is
pulled low. In normal operation, an external pullup resistor with the TPS60310 and TPS60311 is typically used
to connect the PG pin to VOUT. The resistor should be in the 100-kΩ to 1-MΩ range. If the PG output is not used,
it should remain unconnected. Output current at PG (TPS60312, TPS60313) reduces maximum output current
at OUT2.
In snooze mode, the output voltage is sampled at a rate up to 2 ms and is applied to the power-good comparator.
In normal mode, the output voltage is measured continuously.

design procedure
capacitor selection
The TPS6031X devices require only five external capacitors. Their values are closely linked to the required
output current and the output noise and ripple requirements. It is possible to only use 1-µF capacitors of the
same type.
The input capacitor improves system efficiency by reducing the input impedance and stabilizing the input
current.
The minimum required capacitance of the output capacitor (CO) that can be selected is 1 µF. Depending on the
maximum allowed output ripple voltage, larger values can be chosen. Table 1 shows capacitor values
recommended for low output voltage ripple operation. A recommendation is given for the smallest size.

Figure 22. Typical Operating Circuit
For the maximum output current and best performance, five ceramic capacitors of 1 µF are recommended. For
lower currents or higher allowed output voltage ripple, other capacitors can be used. It is recommended that the
input and output capacitors have a minimum value of 1 µF. This value is necessary to assure a stable operation
of the system due to the linear mode. With flying capacitors lower than 1 µF, the maximum output power
decreases. This means that the device works in the linear mode with lower output currents.
output filter design
The power-good output is capable of driving light loads up to 5 mA (see Figure 23). Therefore, the output
resistance of the power-good pin with the output capacitor, can be used as an RC-filter.

Load current sourced by power-good output reduces maximum output current at OUT2. During start-up
(power-good going high) current charging CPG discharges C(OUT2). Therefore, CPG must not be larger than CPG
≤ 0.1 C(OUT2) or the device does not start. By charging CPG through C(OUT2), the output voltage at OUT2
decreases. If the capacitance of CPG is to large, the circuit detects power bad. The power-good output goes low
and discharges CPG. Then the cycle starts again. Figure 24 shows a configuration with an LC-post filter to further
reduce output ripple and noise.

power dissipation
As given in the data sheet, the thermal resistance of the unsoldered package is RθJA = 294°C/W. Soldered on
the EVM, a typical thermal resistance of RθJA(EVM) = 200°C/W was measured.
The thermal resistance can be calculated using equation 4.
Where:
T –T
R θJA + J A
PD
(4)
TJ is the junction temperature.
TA is the ambient temperature.
PD is the power that needs to be dissipated by the device.
The maximum power dissipation can be calculated using equation 5.
PD = VIN × IIN – VO × IO = VIN(max) × (3 × IO + I(SUPPLY)) – VO × IO
(5)
The maximum power dissipation happens with maximum input voltage and maximum output current:
At maximum load the supply current is approximately 2 mA.
PD = 1.8 V × (3 × 20 mA + 2 mA) – 3.3 V × 20 mA = 46 mW
(6)
With this maximum rating and the thermal resistance of the device on the EVM, the maximum temperature rise
above ambient temperature can be calculated using equation 7.
∆TJ = RθJA × PD = 200°C/W × 46 mW = 10°C
(7)
This means that internal dissipation increases TJ by 10°C.
The junction temperature of the device must not exceed 125°C.
This means the IC can easily be used at ambient temperatures up to:
TA = TJ(max) – ∆TJ = 125°C – 10°C = 115°C
(8)
layout and board space
All capacitors should be soldered as close as possible to the IC. A PCB layout proposal for a two-layer board
is shown in Figure 26. Care has been taken to connect all capacitors as close as possible to the circuit to achieve
optimized output voltage ripple performance. The bottom layer is not shown in Figure 26. It only consists of a
ground-plane with a single track between the two vias that can be seen in the left part of the top layer.
