Description
The ZL2106 is an innovative power conversion and management IC that combines an integrated synchronous step-down DC-DC converter with key power management functions in a small package, resulting in a flexible and integrated solution. Zilker Labs Digital-DC™ technology enables unparalleled power management integration while delivering industry-leading performance in a tiny footprint.
The ZL2106 can provide an output voltage from 0.54 V to 5.5 V (with margin) from an input voltage between 4.5 V and 14 V. Internal low RDS(ON) synchronous power MOSFETs enable the ZL2106 to deliver continuous loads up to 6 A with high efficiency. An internal Schottky bootstrap diode reduces discrete component count. The ZL2106 also supports phase spreading to reduce system input capacitance.
Power management features such as digital softstart delay and ramp, sequencing, tracking, and margining can be configured by simple pinstrapping or through an on-chip serial port. The ZL2106 uses the PMBus™ protocol for communication with a host controller and the Digital-DC bus for interoperability between other Zilker Labs devices.

Description
The ZXLD1322 is an inductive DC-DC converter, with an internal switch, designed for driving single or multiple LEDs in series up to a total of 700mA output current.
Applications cover input voltages ranging from 2.5V to 15V. Depending upon supply voltage and external components, this can provide up to 12W of output power.
The device employs a variable 'on' and 'off' time control scheme with adjustable peak switch current limiting and operates in Buck/Boost mode, offering higher power efficiency and lower system cost than conventional PFM buck/boost circuitry.
The device includes the DC-DC converter, a high-side current monitor and an NPN switching transistor to provide an integrated solution offering small PCB size, competitive cost/performance, high power efficiency of DC-DC conversion and maximum LED brightness/reliability. More importantly, it retains design flexibility to add customer specific features.
The feedback control circuitry inside the ZXLD1322 provides excellent load and current regulation, resulting in very stable LED current over the useful life of the battery and over the full operating temperature range.
The LED current can be adjusted from 100% down to 10% of the set value by applying a dc voltage to the ADJ pin and down to 1% by applying a PWM signal. An on-chip LED protection circuit also allows output current to be reduced linearly above a predetermined threshold temperature using an external thermistor at the TADJ pin.
External resistors set nominal average LED current and coil peak current independently.
The device can be shut down by applying a continuous low level dc voltage to the ADJ pin.

Features
*2.5V to 15V Input Voltage Range
*Up to 700mA output current
*Typical efficiency# >80%
*User-defined thermal control of LED output current using external thermistor
*High output current stability over input voltage and temperature
*12μA typical standby current
*LED current adjustable from 100% down to 2%
*Adjustable Soft-Start
*Capable of driving 3 LEDs in series

Applications
*High power LED flashlights
*LED back-up lighting
*General LED lighting

General Description
The AP6015 is the first device in a family of low-noise synchronous step-down DC-DC converters. It is ideally suited for systems powered by either a 1-cell Li-ion battery or a 2- to 3-cell NiCd/ NiMH/ Alkaline battery.
The AP6015 is a synchronous PWM converter with integrated N- and P-channel power MOSFET switches. Compared to the asynchronous topology, synchronous rectification offers the benefits of higher efficiency and reduced component count. The high operating frequency of 1MHz allows small inductor and capacitor to be used. This results in small pcb area. During shut-down, the standby current drops to 1μA or less. The AP6015 is available in the 10-pin MSOP package. It operates over a free-air temperature range of -40oC to 85o C.
