2 / 23 page LM3691 SNVS506H – MAY 2008 – REVISED SEPTEMBER 2011 www.ti.com Connection Diagram Figure 3. 6-Bump Thin DSBGA Package, Large Bump See Package Number YZR0006LCA PIN DESCRIPTIONS Pin DSBGA Name Description Enable pin. The device is in shutdown mode when voltage to this pin is <0.4V and enabled when A1 EN >1.2V. Do not leave this pin floating. Mode Pin: Mode = 1, Forced PWM B1 MODE Mode = 0, ECO Do not leave this pin floating. C1 FB Feedback analog input. Connect directly to the output filter capacitor. (Figure 1) A2 VIN Power supply input. Connect to the input filter capacitor. (Figure 1) B2 SW Switching node connection to the internal PFET switch and NFET synchronous rectifier. C2 GND Ground pin. Absolute Maximum Ratings (1) (2) VIN Pin to GND −0.2V to 6.0V EN, MODE, FB, SW pins (GND −0.2V) to VIN + 0.2V Junction Temperature (TJ-MAX) +150°C Storage Temperature Range −65°C to +150°C Continuous Power Dissipation (3) Internally Limited Maximum Lead Temperature 260°C (Soldering, 10 sec.) ESD Rating (4) Human Body Model 2 kV Machine Model 200V (1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical Characteristics tables. (2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications. (3) Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at TJ = 150°C (typ.) and disengages at TJ = 130°C (typ.). (4) The Human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. The machine model is a 200 pF capacitor discharged directly into each pin.
