LP5952TL-1.3EV

User's Guide SNVA188B – November 2006 – Revised April 2013 AN-1531 LP5952 Evaluation Board 1 Introduction This evaluation board is designed to enable independent evaluation of the LP5952 electrical performance. Each board is pre-assembled and tested in the factory. The evaluation kits are available in four output voltage options for the DSBGA package: LP5952TL-1.2EV, LP5952TL-1.3EV, LP5952TL-1.5EV and LP5952TL-1.8EV and one output voltage option for the COL USON package: LP5952LC-1.5EV. For other voltage options, the device can be ordered from LP5952 product folder on the TI website. The board contains the LP5952 and input and output capacitors connected to GND. 2 General Description The LP5952 converts higher input voltages connected to the power input voltage pin VIN to lower output voltages while consuming low quiescent current. The bias input voltage VBATT supplies internal circuitry. The LP5952 is capable of operating with input voltage ranges from 0.7V ≤ VIN ≤ 4.5V and 2.5V ≤ VBATT ≤ 5.5V for fixed output voltage options from 0.5V to 2.0V. The LP5952 can supply a maximum output current of 350mA and is particularly suitable for portable, battery-powered systems. It also features internal protection against short-circuit and over-temperature conditions. The power input voltage applied between VIN and GND should be at least 0.2V above the output voltage and the bias input voltage applied between VBATT and GND should be at least 1.5V above the output voltage (with a minimum of 2.5V) to operate the device within operating conditions. Input connections should be kept reasonably short (
