SLVS585A – JULY 2005 – REVISED FEBRUARY 2009 TERMINAL FUNCTIONS TERMINAL I/O DESCRIPTION NAME NO. AGND 9 I Analog ground, connect to GND and PGND Enable. A logic high enables the converter; logic low forces the device into shutdown mode reducing the EN 4 I supply current to less than 2 µA. Feedback pin for the fixed output voltage option. For the adjustable version, an external resistive divider FB 10 I is connected to this pin. The internal voltage divider is disabled for the adjustable version. GND 11, 12 I Ground LBI 7 I Low-battery input LBO 6 O Open-drain, low-battery output. This pin is pulled low if LBI is below its threshold. Power good comparator output. This is an open-drain output. A pullup resistor should be connected PG 13 O between PG and VOUT. The output goes active high when the output voltage is greater than 98.4% of the nominal value. PGND 1, 16 I Power ground. Connect all power grounds to this pin. Connect the inductor to this pin. This pin is the switch pin and connected to the drain of the internal SW 14, 15 O power MOSFETS. Input for synchronization to external clock signal. Synchronizes the converter switching frequency to an external clock signal with CMOS level: SYNC 5 I SYNC = HIGH: Low-noise mode enabled, fixed frequency PWM operation is forced SYNC = LOW (GND): Power save mode enabled, PFM/PWM Mode enabled VIN 2, 3 I Supply voltage input (power stage) VINA 8 I Supply voltage input (support circuits) Thermal pad Connect to AGND Copyright © 2005–2009, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Link(s): TPS62110 TPS62111 TPS62112 TPS62113 |
