About This Product

■Summary

The MP28163 is a high efficiency, low quiescent current buck-boost converter that operates with input voltages above, below, or equal to the output voltage. This IC provides a power solution for products powered by single-cell Li-ion or multi-cell alkaline battery applications where the output voltage is within the battery voltage range. The MP28163 uses current mode, fixed frequency PWM control for optimal stability and transient response. Fixed 1.1MHz switching frequency and integrated low RDS (ON) N-channel and P-channel MOSFETs minimize solution footprint while maintaining high efficiency The MP28163 has an optional pulse-skipping mode that reduces switching frequency under light load conditions to maximize battery life. In other low-noise applications where variable frequency power-save modes can cause failures, the logic control input MODE pin forces PWM operation at a fixed frequency under all load conditions. The MP28163 operates with an input voltage of 2V to 5.5V and provides an adjustable output voltage (1.5V to 5V). With a 2.7V to 5.5V input, it can deliver up to 1.3A of current to the load at a 3.3V output voltage. The MP28163 is available in a small QFN10 - 3 x 3mm package.

■Features and benefits

・High efficiency of up to 95% ・Load disconnection during shutdown ・Input voltage range: 2V to 5.5V ・Output voltage adjustable from 1.5V to 5V ・3.3V/1.3A load capability at VIN of 2.7V to 5.5V ・1.1MHz switching frequency ・Pulse skip mode at light load ・Typical 70μA quiescent current ・Inner loop compensation for fast response ・Internal soft start ・OTP, Hiccup SCP ・Delivered in a small 3 x 3mm QFN10 package

■Available product numbers

・MP28163GQ-P MP28163GQ-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
