Milpitas, CAs, CA, Milpitas, December 19, 2013, launched high efficiency, 4MHz synchronous antihypertensive regulator LTC3615 and LTC3615-1 new high reliability Sexual H-class and military MP levels, these devices use a constant frequency, current mode architecture. The internal switch with a very low resistance enables each channel of the LTC 3615 to provide a continuous output current of up to 3A, while its low pressure difference can provide an output voltage from 0.6V to only a few millivolts of a low of Vin. LTC3615 works within 2.25V to 5.5V input voltage range, which is ideal for single-cell lithium-ion battery applications and 3.3V and 5V intermediate bus systems. Its switching frequency is user programmable, ranges from 400 kHz to 4 MHz, thereby allowing for use in slimming and low cost capacitors and inductors. The LTC3615 provides a phase shift between an optional 0o / 90o / 180o channel, while the LTC3615-1 provides an optional 140 ° / 180 ° phase shift. Its fast switching capability combines very small 4mm x 4mm QFN-24 packages or heat-resistant TSSOP-24 packages, providing a very compact solution for a dual output application that requires up to 3A.
The LTC3615 uses RDS (ON) only 55MΩ and 75MΩ internal switch to provide up to 94% efficiency. BURST MODE® works to minimize the light load efficiency and extend the running time of battery-powered applications to maximize light load efficiency. An adjustable burst mode clamp makes the designer to optimize light load efficiency. The LTC3615 can be configured to work with pulse jump or in consecutive mode as minimal noise, thereby reducing noise and potential RF interference. The programmable switching conversion rate further reduces the potential noise problem. Optional 0?, 90 or 180 in the two channels, the phase shift minimizes the input current ripple and output voltage ripple. The LTC3615 provides inputs for tracking capabilities and DDR storage mode, in which the device can provide / absorb ± 1.5A current. Other features include optional active voltage positioning (AVP), good power supply voltage monitors, external synchronization capabilities, and overheating protection.
LTC3615 and LTC3615-1 use 4 mm x 4mm QFN-24 package and 24 lead heat resistance enhanced TSSOP package. The high-reliability H-level version is guaranteed to meet the performance specifications in the work junction temperature of -40 ° C to 150 ° C, and thousands of batch prices are $ 5 and $ 5.35, respectively. Military MP-level versions are guaranteed to meet performance specifications within -55 ° C to 150 ° C, and thousands of batch prices are $ 12.55 and $ 13, respectively. All versions have stock supplies. For more information, please visit www.linear.com.cn/product/ltc3615.
