DEMO MANUAL DC1562B LTC699X-X TimerBlox: Oscillators, One Shots, PWM, Delay, Power on Reset Description Demonstration circuit 1562B is an engineering tool to design and evaluate the LTC699X-X family of TimerBlox(R) circuits. The center section of the board contains a preconfigured TimerBlox function. DC1562B comes in twelve timing function variations as outlined in Table 1. Surrounding the center board is a playground prototyping area. The prototyping area has pads for DIP-8, S8, MS8, or S6 packages with bread boarding connections to each pin and two convenient power buses and ground bus surrounding the entire area. This area is for conditioning signals to control the timer function and for adding loads controlled in time. The center part of the board can be detached as a streamlined circuit, to combine with a pre-existing circuit. For application flexibility, a provision is made for buffering and inverting the output of the timer. An optional NC7W04P6X SC70 package dual inverter can be added at U2 to provide this functionality. Design files for this circuit board are available at http://www.linear.com/demo L, LT, LTC, LTM, Linear Technology, TimerBlox and the Linear logo are registered trademarks of Linear Technology Corporation. All other trademarks are the property of their respective owners. Using the Demo Board To understand the simplicity and flexibility of the TimerBlox function, download the appropriate data sheet from the LTC website, www.linear.com. Each evaluation board comes with a TimerBlox part, decoupling cap and a bulk decoupling 10F tantalum cap. Resistors are also installed that configure the TimerBlox device so that they are ready to use by simply adding power. Changing the default configuration of the demo board is a simple matter of determining a few new resistor values. Simply select a pair of resistor values for the DIV value from the data sheet DIV table, calculate the value of RSET required, replace the resistor on the board, apply power, and go! Single supply power between 2.25V and 5.5V and ground must be supplied directly to the center board. The outer prototyping section of the board can be used with single or dual supplies as required. When using the prototyping area, the outermost trace, which is ground, must be connected (hand wired) to the ground on the center board section. All input and output holes are sized for 65mil turret terminals, or wires can be soldered in the holes directly. Changing the timer configuration requires changing resistor values on the center board. The resistor lead holes can accept "pressed-in" DIP sockets, or resistors can be soldered directly in the holes. Pads for 0805 surface mount resistors are also included at each position where a leaded resistor could be used. Pads are also included for three 25-turn trim pots which can be used to replace RSET (R8) for master oscillator frequency adjustment, PSF in (R10) for voltage controlled options, and RDEV (R7) for frequency divider control to permit real-time adjustments while running. dc1562bfa 1 DEMO MANUAL DC1562B Using the Demo Board Table 1.
