EN 2 I Enable pin.Typical turn-on threshold voltage is 1.3 V. Typical turn-off threshold voltage is 1.0 V. GND G Ground and thermal pad of the device. Use proper number of vias to connect to ground plane. 6 7 8 LL B Output of converted power. Connect this pin to the output Inductor. 9 10 11 Soft-start and mode selection. Connect a resistor to select soft-start time using Table 1. The soft-start time MODE 20 I is detected and stored into internal register during start-up. Open drain power good flag. Provides 1-ms start-up delay after VFB falls in specified limits. When VFB PGOOD 3 O goes out of the specified limits PGOOD goes low after a 2-µs delay Redundant overvoltage protection (OVP) input. Use a resistor divider to connect this pin to VOUT. ROVP 5 I Internally pulled down to GND with 1.5-M Ω resistor. Float this pin or connect to GND if redundant OVP is not needed. Switching frequency selection. Connect a resistor to GND or VREG to select switching frequency using RF 22 I Table 2. The switching frequency is detected and stored during the startup. OCL detection threshold setting pin. ITRIP = 10 µA at room temperature, 3000 ppm/°C current is sourced and set the OCL trip voltage as follows. TRIP 21 I space VOCL=VTRIP/32 (VTRIP ≤ 2.4 V, VOCL ≤ 75 mV) Supply input for high-side FET gate driver (boost terminal). Connect capacitor from this pin to LL node. VBST 4 P Internally connected to VREG via bootstrap MOSFET switch. VDD 19 P Controller power supply input. VDD input voltage range is from 4.5 V to 25 V. VFB 1 I Output feedback input. Connect this pin to VOUT through a resistor divider. 12 13 14 VIN P Conversion power input.The conversion input voltage range is from 1.5 V to 22 V. 15 16 17 (1) I=Input, O=Output, B=Bidirectional, P=Supply, G=Ground Copyright © 2012–2013, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: TPS53318 TPS53319 |
