Dual Interleaved Regulators with Independent Outputs Connection Diagram Figure 2. 16-Lead TSSOP (Top View) Pin Functions Pin Description PIN NAME DESCRIPTION APPLICATIONS INFORMATION 1 VIN Input Supply Input to the startup regulator. The operating input range is 13V to 100V with transient capability to 105V. 2 COMP1 PWM Control, Controller 1 The COMP1 input provides voltage feedback to the PWM comparator inverting input of Controller 1 through a 3:1 divider. The OUT1 duty cycle increases as the COMP1 voltage increases. An internal 5K Ω pull-up resistor to +5.0V provides bias current to an opto-coupler transistor. 3 CS1 Current Sense Input, Controller 1 Input for current mode control and the current limit sensing. If the CS1 pin exceeds 0.5V the OUT1 pulse is terminated producing cycle-by-cycle current limiting. External resistance connected to CS1 will adjust (increase) PWM slope compensation. This pin's voltage must not exceed 1.25V. 2 Submit Documentation Feedback Copyright © 2005, Texas Instruments Incorporated Product Folder Links: LM5032 |
