Product Description

TCS4837 is an I2C Programmable, high efficiency, 2.1MHz, Synchronous Buck converter that operates in wide input voltage range from 2.7V to 5.5V. The output Voltage could be programmed from 0.7125V to 1.5V. Very low standby current ensure high efficiency in light load PFM mode. The forced PWM mode could be set to avoid application problems caused by low switching frequency. A COT (Constant On-Time) structure is adaptive to achieve the fixed switching frequency and fast load transient response. TCS4837 provides up to 5A output current with Integrated 28m Ω (high side) and 18m Ω (low side) power switch.

TCS4837 also implement an internal soft-start and cycle-by-cycle over current protection function. In addition, the input UVLO and OVP protection, Thermal shutdown protection.
