Product Description:
Manufacturer Part Number: TPS51125, dual-synchronous buck controller, 36V, 100mA, 1.6ms, QFN
Description:
The
TPS51125 is a cost effective, dual-synchronous buck controller targeted for notebook system power supply solutions. The TPS51125 provides 5-V and 3.3-V LDOs and requires few external components. The 270-kHz VCLK output can be used to drive an external charge pump, generating gate drive voltage for the load switches without reducing the main efficiency. The TPS51125 supports high efficiency, fast transient response and provides a combined power-good signal. Out-of-Audio mode light-load operation enables low acoustic noise at much higher efficiency than conventional forced PWM operation. The TPS51125 operates with supply input voltages ranging from 5.5 V to 28 V and supports output voltages from 2 V to 5.5 V. The TPS51125 is available in a 24-pin QFN package.
