8 / 14 page MP2158A – 1A, 6V, 1.5MHz SYNCHRONOUS STEP-DOWN CONVERTER MP2158A Rev. 1.02 www.MonolithicPower.com 8 6/30/2016 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2016 MPS. All Rights Reserved. PIN FUNCTIONS Pin # Name Description 1 EN On/off control. 2 FB Feedback. An external resistor divider from output to AGND tapped to FB sets the output voltage. 3 AGND Analog ground for internal control circuit. 4 OUT Input sense for output voltage. 5 PGND Power ground. 6 SW Switch output. 7 VIN Supply voltage. The MP2158A operates from a +2.5V to +6V unregulated input. C1 is needed to prevent large voltage spikes from appearing at the input. 8 PG Power good indicator. The output of PG is an open-drain structure with an internal pull-up resistor to VIN. PG is pulled up to VIN when the FB voltage is within ±10% of the regulation level. If the FB voltage is out of that regulation range, it is low. |
