ZXCT1011 is a high side current sense monitor. Using this type of device eliminates the need to disrupt the ground plane when sensing a load current. The ZXCT1011 takes the voltage developed across a current shunt resistor and translates it into a proportional output current. A user defined output resistor scales the output current into a ground referenced voltage. A current reference resistor, external to the IC, results in an improved temperature coefficient compared to the ZXCT1009. The wide input voltage range of 2.5V down to as low as 2.5V make it suitable for a range of applications. With a minimum operating current of just 4uA, combined with its SOT23-5 package make it suitable for portable battery equipment too.

This product is a PFM inductive boost converter designed for driving 2, 3 or 4 series connected white LEDs from a Li-Ion cell and up to 8 LEDs from a 5V supply. It operates from an input supply of between 2.5V and 5.5V and provides an adjustable output current of up to 50mA. The ZXLD1937 includes the output switch and peak current sense resistor, and can operate with a maximum output voltage of 28V. Typical quiescent current is 60μA and a shutdown function is provided to reduce this current to less than 500nA in the 'off' state.

The ZXGD3001E6 is a high-speed non-inverting single MOSFET gate driver capable of driving up to 9A into a MOSFET or IGBT gate capacitive load from supply voltages up to 12V. With typical propagation delay times down to 3ns and rise/fall times down to 11ns this device ensures rapid switching of the power MOSFET or IGBT to minimize power losses and distortion in high current fast switching applications.

The ZXGD3003E6 is a high-speed non-inverting single MOSFET gate driver capable of driving up to 5A into a MOSFET or IGBT gate capacitive load from supply voltages up to 40V. With typical propagation delay times down to 2ns and rise/fall times down to 9ns this device ensures rapid switching of the power MOSFET or IGBT to minimize power losses and distortion in high current fast switching applications. The ZXGD3003E6 is inherently rugged to latch-up and shoot-through, and its wide supply voltage range allows full enhancement to minimize on-losses of the power MOSFET or IGBT. Its low input voltage requirement and high current gain allows high current driving from low voltage controller ICs, and the optimized pin-out SOT23-6 package with separate source and sink pins eases board layout, enabling reduced parasitic inductance and independent control of rise and fall slew rates.

This design note introduces a push-pull inverter for backlighting LCD displays. It has the following features: compact size, high efficiency, wide operating voltage range, and adjustable contrast.

The ZXLB1600 inductive switching boost converter accepts an input voltage of between 1.6V and 5.5V and provides an adjustable output voltage of up to 28V for LCD and OLED bias. The device contains an output switch and a second switch to isolate the coil from the input to provide true isolation in shutdown mode. The output can be adjusted by means of an externally applied dc voltage, a PWM control signal, or external feedback resistors and can supply typically 10mA of output current at maximum output voltage. Higher current is available at lower output voltages. The input voltage range accepts a number of battery solutions, including dual dry cell and single Li-Ion cells and PFM operation mode allows the output to be regulated with high efficiency under light or no load conditions. The switching frequency range permits the use of miniature surface mount inductors. A low battery comparator is provided to indicate when the input voltage has fallen to within ±2% of a preset threshold. This threshold is set internally, but can be adjusted externally to any voltage within the supply voltage range.
