Intersil claims to have smallest pico-projector

Description

The ISL9307 is an integrated mini Power Management IC (mini-PMIC) ideal for applications for powering
low-voltage microprocessor or multiple voltage rails with a battery as an input source, such as a single Li-ion or Li-polymer. ISL9307 integrates two high-efficiency, 3MHz, synchronous step-down converters (DCD1 and DCD2) and two low-input, low-dropout linear regulators (LDO1 and LDO2).

The 3MHz PWM switching frequency allows the use of very small external inductors and capacitors. Both
step-down converters can enter skip mode under light load conditions to further improve efficiency and maximize battery life.

The ISL9307 features EN pins for each channel, thus allowing startup delay for power sequencing.

The ISL9307 also provides two 300mA low-dropout (LDO) regulators. The input voltage range is 1.5V to 5.5V, which allows them to be powered from one of the on-chip step-down converters or directly from a battery. The default LDO power-up output comes with factory pre-set fixed output voltage options between 0.9V and 3.3V.

The ISL9307 is available in a 4mmx4mm 16 Ld TQFN.

Intersil claims to have smallest pico-projector

Intersil has developed aĀ pico projector system, which it claims is theĀ smallest production-ready LED liquid crystal on silicon (LCoS) based design.

Developed forĀ embedded or accessory pico projector applications,Ā the firmā€™sĀ reference designĀ is based onĀ Micronā€™s E330Ā 5.5 cubic cm qHD optical engine

TheĀ platform,Ā Pico-qHD,Ā uses Intersilā€™sĀ ISL97901Ā buck/boost RGGB LED driver. The supplier said the deviveĀ maintains the highest image quality with precise current control.

ā€œA 2.0mA resolution provides consistent white balance setting, yielding uniformity over production units and throughout the life of projectors,ā€ said Intersil.

The system, which comes onĀ a 1.7Ā x 2in PCB,Ā can drive up to 1.5A LED current, making it compatible with a variety of high power LEDs, and enabling pico projector engines with brightness levels exceeding 20 lumens.
