TPS65086x Schematic and Layout Checklist TPS650860

Demonstration circuit 1401A is an adjustable 500mA linear regulator featuring the LT3085. Architected as a precision current source and voltage follower, the LT3085 can be used in many applications requiring up to 500mA output current, adjustability down to 0V at the output and no heat sink. The device brings out the collector of the pass transistor to allow low dropout operation when used with multiple supplies. The demo board operates with an input voltage range from 1.7V to 25V (the maximum output voltage is limited by the output capacitor's voltage rating) and provides a jumper-selectable output voltage of 1.2V, 1.8V, 2.5V, 3.3V, 5V or a user-defined value. For the LT3085 to regulate properly, the voltage on the control pin (VCONTROL) must be more than approximately 1.2V greater than the output voltage.

In this topology: the UCC28051 is a boost transition mode (TM) power factor corrector (PFC): which can rectify an AC input line voltage to 380V DC; the resonant LLC stage UCC25600 regulates the output to 24V/2A for an audio amplifier with feedback to the LLC controller: and 48V for the LED driver input. The flyback with UCC28610 in parallel generates 5V/3A for the system board and 5V/1A for standby power. In the LED driver stage: the 48V input voltage requires another front end boost stage to boost the output voltage to 80V: which connects to the eight-channel TLC5960 with 20LEDs at 120mA per string.This technique is the most common type of current LED backlight; the LLC design is easily implemented. The intelligent headroom voltage monitor (oriHVM™) automatically minimizes the power loss caused by the LED forward voltage change. Only a single additional resistor regulates the boost dc-dc output voltage.

In addition to their actual operation parameter transconductance, active electronic key components such as vacuum tubes, field effect transistors, and bipolar transistors demonstrate diverse negative

The HMC345ALP3E is a broadband non-reflective GaAs MESFET SP4T switch in a low cost leadless surface mount packages. Covering DC to 8 GHz, this switch offers high isolation and low insertion loss. This switch also includes an on board binary decoder circuit which reduces the required logic control lines to two. The switch operates using a positive control voltage of 0/+5V, and requires a fixed bias of +5V.* Blocking capacitors are required at ports RFC and RF1, 2, 3, & 4. Their value will determine the lowest transmission frequency.APPLICATIONSThis switch is suitable for usage in DC - 8.0 GHz 50-Ohm or 75-Ohm systems: Broadband Fiber Optics Switched Filter Banks Wireless below 8 GHz

The ADS603 is a 10MHz 12-bit analog-to-digital converter with a ±1.25V input range. Many applications call for a higher input range such as ±2.5V. A resistor divider can be used as an input attenuator to increase the input range. The OPA620 can be used to buffer the input attenuator for high-source-impedance applications. Suggested component values and measured performance results a
