Description:
The TPS6281x-Q1 is family of pin-to-pin 1-A, 2-A, 3-A and 4-A synchronous step-down DC/DC converters. All devices offer high efficiency and ease of use. The TPS6281x-Q1 family is based on a peak current mode control topology. TPS6281x-Q1 is designed for automotive applications such as Infotainment and advanced driver assistance systems. Low resistive switches allow up to 4-A continuous output current at
high ambient temperature. The switching frequency is externally adjustable from 1.8 MHz to 4 MHz and can also be synchronized to an external clock in the same frequency range.
Features:
• Input voltage range: 2.75 V to 6 V
• Family of 1 A, 2 A, 3 A and 4 A
• Quiescent current 15-µA typical
• Output voltage from 0.6 V to 5.5 V
• Output voltage accuracy ±1% (PWM operation)
• Adjustable soft start
• Forced PWM or PWM and PFM operation
• Adjustable switching frequency of
1.8 MHz to 4 MHz
• Precise ENABLE input allows
– User-defined undervoltage lockout
– Exact sequencing
• 100% duty cycle mode
• Active output discharge
• Spread spectrum clocking - optional
• Power good output with window comparator
• Package with wettable flanks
