DESCRIPTION
The TPS6024x is a switched capacitor voltage
converter, ideally suited for VCO and PLL applications
that require low noise and tight tolerances. Its dual-cap
design uses four ceramic capacitors to provide ultralow
output ripple yet high efficiency, while eliminating the
need for inefficient linear regulators.

A wide input supply voltage range of 2.7 V to 5.5 V
makes the TPS6024x ideal for lithium-based battery
applications. The TPS60240/2/3 operates down to
1.8 V, supporting a 3.3-V, 2.7-V, 3-V output from
two-cell, nickel- or alkaline-based chemistries. The
devices work equally well for low EMI dc/dc step-up
conversion without the need for an inductor. The high
switching frequency (typical 160 kHz) promotes the use
of small surface-mount capacitors, saving board space.
The converter’s shutdown mode conserves battery
energy.

detailed description
operating principle
The TPS6024x charge pump is a fixed-frequency, dual-phase charge pump that provides 25 mA of continuous
supply current for low-noise applications such as VCOs used in cell phones and wireless appliances.
Low-noise operation results from using a proprietary dual-phase charge pump topology that relies on an
operational amplifier in the feedback loop to reduce ripple. During the first phase, C is charged to the supply
1
voltage. Terminal C is connected to V , and C isconnectedtoGND. Inthesecondphase, C isconnected
1+
IN
1–
1+
1–
to the output of the operational amplifier, and C is connected to V
. The operational amplifier then adjusts
OUT
its output until the output V
delivers the correct voltage to make the resistor divided feedback point equal
OUT
to the reference voltage. During this second phase, C is charged to supply voltage. Terminal C is connected
to GND, and C is connected to V . Phase one is then repeated with C , now acting to provide charge to the
2
2–
2+
IN
2
output in place of C , which is connected to the supply. The dual-phase operation lowers the output ripple
1
voltage significantly compared to a standard single-phase charge pump. In addition, the linear feedback of the
operational amplifier eliminates the ripple during discharge of the output capacitor (C ).
O
shutdown
Driving EN low disables the converter. This disables the internal circuits and reduces input current to typically
0.1 µA. In this mode, the load is disconnected from the supply voltage. The device exits shutdown once EN is
set to a high level.
start-up procedure
The converter is enabled when EN is set from logic low to high. The start-up time to reach 90% of the nominal
output voltage is typically 0.5 ms at load currents lower than 10 mA and with an output capacitor of 1 µF.
Increasing the values of C delays the start-up time.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS
&
no Sb/Br)
-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
