4 / 26 page TPS62065, TPS62067 SLVS833A – MARCH 2010 – REVISED MAY 2010 www.ti.com ELECTRICAL CHARACTERISTICS (continued) Over full operating ambient temperature range, typical values are at TA = 25°C. Unless otherwise noted, specifications apply for condition VIN = EN = 3.6V. External components CIN = 10mF 0603, COUT = 10mF 0603, L = 1.0mH, see the parameter measurement information. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT OSCILLATOR fSW Oscillator frequency 2.9 V ≤ VIN ≤ 6 V 2.6 3 3.4 MHz OUTPUT Vref Reference voltage 600 mV PWM operation, MODE = VIN , VFB(PWM) Feedback voltage PWM Mode –1.5 0 1.5 2.9 V ≤ VIN ≤ 6 V, 0 mA load % Feedback voltage PFM mode, device in PFM mode, voltage positioning active(2) VFB(PFM) 1 Voltage Positioning Load regulation -0.5 %/A VFB Line regulation 0 %/V Activated with EN = GND, 2.9V ≤ VIN≤ 6V, 0.8 ≤ 75 200 1450 R(Discharge) Internal discharge resistor Ω VOUT≤ 3.6V tSTART Start-up time Time from active EN to reach 95% of VOUT 500 ms (2) In PFM mode, the internal reference voltage is set to typ. 1.01×Vref. See the parameter measurement information. PIN ASSIGNMENTS TERMINAL FUNCTIONS TERMINAL I/O DESCRIPTION NO. NAME SON 2x2-8 PGND 1 PWR GND supply pin for the output stage. This is the switch pin and is connected to the internal MOSFET switches. Connect the SW 2 OUT external inductor between this terminal and the output capacitor. AGND 3 IN Analog GND supply pin for the control circuit. Feedback pin for the internal regulation loop. Connect the external resistor divider to this pin. FB 4 IN In case of fixed output voltage option, connect this pin directly to the output capacitor This is the enable pin of the device. Pulling this pin to low forces the device into shutdown EN 5 IN mode. Pulling this pin to high enables the device. This pin must be terminated MODE: MODE pin = high forces the device to operate in fixed frequency PWM mode. MODE MODE IN pin = low enables the Power Save Mode with automatic transition from PFM mode to fixed frequency PWM mode. This pin must be terminated. 6 Open PG: Power Good Open Drain output. Connect an external pull up resistor to a rail which is PG Drain below or equal AVIN. Analog VIN power supply for the control circuit. Need to be connected to PVIN and input AVIN 7 IN capacitor. PVIN 8 PWR VIN power supply pin for the output stage. For good thermal performance, this PAD must be soldered to the land pattern on the pcb. Power PAD This PAD should be used as device GND. 4 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated Product Folder Link(s) :TPS62065 TPS62067 |
