TPS60242170 uVrms Zero-Ripple Switched Cap Boost Converter With Fixed 2.7V Output For VCO Supply | Voltage Regulators - DC DC Switching Regulators | 3 | Active | The TPS6024x devices are a family of switched capacitor voltage converters, ideally suited for voltage-controlled oscillator (VCO) and phase-locked loop (PLL) applications that require low noise and tight tolerances. Its dual-cap design uses four ceramic capacitors to provide ultra-low output ripple with high efficiency, while eliminating the need for inefficient linear regulators.
The TPS6024x devices operate down to 1.8 V, supporting a 3.3-V, 2.7-V, 3-V output from two-cell, nickel- or alkaline-based chemistries, whereas the TPS60241 works with 2.7-V to 5.5-V input voltage providing a 5-V output. 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 shutdown mode of the converter conserves battery energy.
The devices are thermally protected and current-limited for reliable operation even under persisting fault conditions. Normal quiescent current (ground pin current) is only 250 µA, and typically 0.1 µA in shutdown mode. The TPS6024x devices come in a thin, 8-pin VSSOP package with a component height of only 1.1 mm.

TPS60250High efficiency charge pump for 7 WLEDs with I2C interface with 0x77 I2C slave address | LED Drivers | 3 | Active | The TPS60250/2 are high efficiency, constant frequency charge pump DC/DC converters that use dual mode 1× and 1.5× conversions to maximize efficiency over the input voltage range. The devices drive up to five white LEDs for the main display and up to two white LEDs for the sub display with regulated constant current for uniform intensity. By utilizing adaptive 1×/1.5× charge pump modes and very low-dropout current regulators, the TPS60250/2 achieve high efficiency over the full 1-cell lithium-battery input voltage range.
Four enable inputs, ENmain, ENsub1, ENsub2, and ENaux, available through the I2C, are used for simple on/off controls for the independent main, sub1, sub2, and DM5 displays, respectively. To lower the operating current when using one sub display LED, the devices provide completely separate operation for the sub display LEDs.
The TPS60250/2 are available in a 16-pin 3mm x 3mm thin QFN.

TPS60301Single cell to 3.0V, 20mA dual output, high efficiency charge pump with open-drain power-good output | Voltage Regulators - DC DC Switching Regulators | 3 | Active | The TPS6030x devices are a family of switched-voltage converters designed specifically for space-critical battery powered applications.
The TPS6030x 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).
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 3× or 4× conversion mode.
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 output 1 is 20 mA and the load at output 2 is 10 mA.
The devices operate in the newly developed LinSkip mode. In this operating mode, the device switches seamlessly from the power saving, pulse-skip mode at light loads, to the low-noise, constant-frequency linear-regulation mode, when the output current exceeds the device-specific output current threshold.
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.
