B, 03-Aug-09 Vishay Siliconix SiP12503 PIN CONFIGURATION AND TRUTH TABLE PIN FUNCTIONS XSHD (Pin 1) XSHD is a logic-level shutdown control pin. When XSHD is low, the IC’s switching is disabled, and an antiringing switch is connected between LX and VIN. When XSHD is high, the IC is working in normal operation. VIN (Pin 2) VIN is the pin connected to battery input voltage. At start-up, SiP12503 is powered from the voltage at the VIN pin. Once VOUT exceeds VIN, the SiP12503 is powered from VOUT. This increases the drive to the gate of the internal power switch, to allow higher maximum output currents and higher converter efficiency. VOUT (Pin 3) VOUT is the output of the boost converter and also the power source for the IC. FB (Pin 4) FB is the output voltage feedback pin via an external resistor divider. The feedback voltage is nominally 0.6 V. GND (Pin 5) GND is the ground pin for signal and power ground. LX (Pin 6) LX connects to the drain of the internal power MOSFET (boost switch). Externally, the LX pin should be connected to the boost inductor and Schottky diode. If the inductor current falls to zero, or XSHD is low, an internal antiringing switch is short from LX to VIN to minimize EMI. 2 3 6 5 4 1 PowerPAK MLP33-6 Top View FB GND LX VOUT VIN XSHD ORDERING INFORMATION Part Number Temperature Range Marking SiP12503DMP-T1-E3 - 40 °C to 85 °C 2503 PIN DESCRIPTION Pin Number Name Function 1 XSDH Logic controlled shutdown Input, XSHD = high: normal operation, XSHD = low: shutdown 2 VIN Input voltage 3 VOUT Output of the boost converter and power source for the IC-battery 4 FB Output voltage feedback pin 5 GND Signal and power ground 6 LX Switch pin |
