The AS1382 is a high-efficiency, constant-frequency synchronous buck converter available as adjustable- and fixed voltage-version. 1.1 Kit Content Figure 1: Kit Content Item Comment AS1382 Evaluation Board High-efficiency, constant-frequency synchronous buck converter ams Eval Kit Manual [v1-00] 2015-Mar-23 Page 3 Document Feedback AS1382 Standard Board 2 Getting Started Drive the AS1382 synchronous buck converter only with the recommended settings and values as described in the datasheet. Please check www.ams.com for the latest version. A detailed overview of AS1382 Evaluation Board is given in chapter 3, Hardware Description. 3 Hardware Description The Evaluation Board has to be supplied via the pins VIN and GND in the range of 2.7V up to 5.5V. For enabling the device jumper “EN” (J1) must be set to “on”, section F in Figure 2. Please use the “VOUT” (BU4) or “Load” (J2) connector for connecting a load to Vout. AS1382 supports output voltages between 0.6125 and 3.35V and additionally the device is available with 2MHz, 3MHz, or 4MHz switching frequency. The offered variants of AS1382 Evaluation Kit are stated under chapter 4, Ordering & Contact Information. ams Eval Kit Manual [v1-00] 2015-Mar-23 Page 4 Document Feedback AS1382 Standard Board Figure 2: Evaluation Board Overview B A D C E G F I H J K M L Label Name Designator Description Info A VIN BU1 Supply voltage Voltage range from 2.7V to 5.5V Connect to the pos. terminal of the supply B VOUT BU4 Output Voltage Designated for load connection C VIN TP1 Supply voltage measurement point D EN TP2 Enable measurement point E GND TP6 Ground measurement point F EN J1 Enable ON: AS1382 is enabled OFF: AS1382 is put into shutdown mode ams Eval Kit Manual [v1-00] 2015-Mar-23 Page 5 Document Feedback AS1382 Standard Board Label Name Designator Description G LN J3 Mode selection Info No Jumper: Connect a valid enable signal to Enable Input (BU2) EN pin should not be left floating ON: The AS1382 operates in Low-Noise Mode (LowRipple) OFF: The AS1382 operates in High-Efficiency Mode H AS1382 U1 6-pin WL-CSP High-efficiency, constantfrequency synchronous buck converter I Load J2 Load connector Designated for load connection J Mode TP3 Mode measurement point K VOUT TP5 Output Voltage measurement point L EN BU2 Enable Input A logic low on this pin puts the device in shutdown mode. “EN” Jumper (J1) must be removed when using this input to enable/disable the chip.
