The LT3491 is an efficient Li-Ion driver that provides up to 600mA of drive current for four white LEDs. The driver features a unique high side LED current sense that enables the LED string to be connected with one side to ground, which simplifies LED connection. The driver uses a fixed frequency step-up DC/DC converter that is specifically designed to drive up to six white LEDs in series from a Li-Ion cell. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.

The LT1073 is a versatile micropower DC/DC converter that only requires three external components to deliver a fixed output of 5V or 12V. With a minimum supply voltage of 1V, it can be used in applications where the primary power source is a single cell. An on-chip auxiliary gain block can function as a low-battery detector or linear post-regulator. The average current drain of the LT1073-5 used in the typical application circuit is just 135µA unloaded, making it ideal for applications where long battery life is important. The circuit shown can deliver 5V at 40mA from an input as low as 1.25V and 5V at 10mA from a 1V input. The device can easily be configured as a step-up or step-down converter, although for most step-down applications or input sources greater than 3V, the LT1173 is recommended. Switch current limiting is user-adjustable by adding a single external resistor. Unique reverse-battery protection circuitry limits reverse current to safe, nondestructive levels at reverse supply voltages up to 1.6V.

The LTC ®1736 is a synchronous step-down switching regulator controller optimized for CPU power. The output voltage is programmed by a 5-bit digital-to-analog converter (DAC) that adjusts the output voltage from 0.925V to 2.00V according to Intel mobile VID specifications. The 0.8V reference is compatible with future microprocessor generations. The operating frequency (synchronizable up to 500kHz) is set by an external capacitor allowing maximum flexibility in optimizing efficiency. The output voltage is monitored by a power good window comparator that indicates when the output is within 7.5% of its programmed value.
