PM6670ASTR
PM6670ASTR - Brand New STMicroelectronics Power Management Specialized - PMIC
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
Description
The device PM6670AS is a complete DDR2/3 power supply regulator designed to
meet JEDEC specifications.
It integrates a Constant On-Time (COT) buck controller, a 2 Apk sink/source
Low Drop Out regulator and a 15 mA low noise buffered reference.
The COT architecture assures fast transient response supporting both
electrolytic and ceramic output capacitors. An embedded integrator control
loop compensates the DC voltage error due to the output ripple.
Features
■ Switching section (VDDQ)
– 4.5 V to 36 V input voltage range
– 0.9 V, ±1 % voltage reference
– 1.8 V (DDR2) or 1.5 V (DDR3) fixed output voltages
– 0.9 V to 2.6 V adjustable output voltage
– 1.237 V ±1 % reference voltage available
– Very fast load transient response using constant-on-time control loop
– No RSENSE current sensing using low side MOSFETs RDS(ON)
– Negative current limit
– Latched OVP and UVP
– Soft-start internally fixed at 3 ms
– Selectable pulse skipping at light load
– selectable No-Audible (33 kHz) pulse skip mode
– Ceramic output capacitors supported
– Output voltage ripple compensation
■ VTT LDO and VTTREF
– 2 Apk LDO with foldback for VTT
– Remote VTT sensing
– High-Z VTT output in S3
– Ceramic output capacitors supported
– ±15 mA Low noise buffered reference
Applications
■ DDR2/3 memory supply
■ Digital TV system
■ SSTL18, SSTL15 and HSTL bus termination
