ZL9101M Datasheet | Intersil

features internal pensation, internal soft-start, auto-recovery overcurrent protection, an enable option, and pre-biased output start-up capabilities. The ZL9101M is packaged in a thermally enhanced, pact (15mmx15mm) and low profile (3.5mm) over-molded QFN package module suitable for automated assembly by standard surface mount equipment. The ZL9101M is Pb-free and Ro HS pliant. Features - plete Digital Switch Mode Power Supply - Fast Transient Response - External Synchronization - Output Voltage Tracking - Current Sharing - Programmable Soft-start Delay and Ramp - Overcurrent/Undercurrent Protection - PMBus pliant Applications - Server, Tele, and Data - Industrial and Medical Equipment - General Purpose Point of Load Related Literature - See AN2033, “Zilker Labs PMBus mand Set - DDC Products” - See AN2034, “Configuring Current Sharing on the ZL2004 and ZL2006” V DRV 4.5V TO 6.5V 10µF 16V 4.7µF 16V 4.7µF 16V 10µF 16V V IN 4.5V TO 13.2V 2 x 22µF 16V VDRV POWER GOOD OUTPUT ENABLE Ext Sync DDC Bus PG EN VIN (EPAD) VOUT (EPAD) ZL9101M SW (EPAD) PGND (EPAD) FB+ FB3 x 47µF 16V V25 V OUT SYNC DDC SCL Notes: 1. The I2C/SMBus requires pull-up resistors. Please refer to the I2C/SMBus specifications for more details. 2. The DDC bus requires a pull-up resistor. The resistance will vary based on the capacitive loading of the bus (and on the number of devices connected). The 10k default value, assuming a maximum of 100p F per device, provides the necessary 1µs pull-up rise time. Please refer to the Digital-DC Bus section for more details. 3. Additional capacitance may be required to meet specific transient response targets 4. The VR, V25, VDRV, and VDD capacitors should be placed no further than 0.5 cm from the pin. FIGURE 1. 12A APPLICATION CIRCUIT NOTE: Figure 1 represents a typical implementation of the ZL9101M. For PMBus operation, it is remended to tie the enable pin (EN) to SGND.
