Product Introduction
The TLV62565/6 devices are synchronous buck converters optimized for small solution size and high efficiency. The devices integrate switches capable of delivering up to 1.5A output current.
The devices operate with adaptive on-time based on a valley current mode control scheme. Typical operating frequency at medium to heavy loads is 1.5MHz. The devices are optimized to achieve very low output voltage ripple even with small external components, and feature an excellent load transient response.
During light load, the TLV62565/6 automatically enters power save mode at a minimum quiescent current (typical 50μA) to maintain high efficiency across the full load current range. In shutdown, current consumption is reduced to less than 1μA.
The TLV62565/6 provides an adjustable output voltage via an external resistive voltage divider. The output voltage startup ramp is controlled by an internal soft-start, typically 250μs. Power sequencing is also possible by configuring the enable (TLV62565) and power good (TLV62566) pins. Additional features such as overcurrent protection and overtemperature protection are built in. The TLV62565/6 devices are available in a 5-pin SOT-23 package.
